Specifications and website: "EVH 5150III heads and cabinets deliver the holy grail of tone - a truly clean channel, a super-heavy crunch channel and an off-the-scale overdrive channel you simply won’t believe. You get the incredible tones Eddie Van Halen has chased his whole life, as Eddie himself has defined and designed each of the 5150III amplifier’s three channels. Available in black or ivory, with an unmistakable look and sound that’s pure EVH"
5. Cliff: "IMO, it's a very good amp. The build-quality is great and the design is very good. It is similar to the previous versions but voiced a bit different. Personally, I think all of the 5150's have more gain stages than necessary which just makes for unnecessary failure points but the "OMG, this map has sooo many toobz it must sound awesome" marketing makes it understandable. It's incredibly heavy though" Source

7. Cliff: "A 5150 uses a fixed bias with no adjustment. Depending on the tubes used the bias can run from average to cold. The model uses average. Some people like a colder sound. If you prefer your amps biased cold, then reduce the bias parameter to taste" Source

5. Fender website: "In early 1952, the Fender Bassman amplified a great new invention - the Fender Precision Bass guitar. At 50 watts, it competed easily with the common instrumentation of the day: horns, piano, small drum kit, and maybe even an electric guitar through a new 10-watt amp. Through the ’60s and ’70s, the original all-tube tweed 4x10” Bassman was popular with rock, country and blues guitarists as a reliably great-sounding and easy-to-use guitar amp. In the ’90s, Fender released an affordable ’59 Bassman reissue amplifier to great acclaim. Many guitarists, tired of experimenting with preamps, equalizers and effects racks, rediscovered the simple pleasure of plugging into a Fender tube amp. The reissue Bassman’s wide stage coverage, touch-sensitive dynamics and full-frequency swirl make it perfect for building great tone with almost any guitar or effect, and it remains a staple of the Fender guitar amp line to this day"

7. Fenderguru.com: "The Fender Bassman is a legendary guitar amp known to both guitar and bass players. It was introduced in 1951, primarily targeted for bass guitar players and promoted as a bass amp for the Fender Precision Bass guitar, the first mass-produced electric bass guitar ever. During the different eras the Bassman amp came in many different shapes and configurations. Few other models experienced so many changes in terms of looks and tone. Unfortunately the Bassman was one of the first amps that CBS laid their hands on after buying the company from Leo Fender. A couple of things in the circuitry were immediately changed in 1965 when the AA165 and AB165 replaced the AA864, which by amp idealists is considered the best Bassman circuit of all times together with the legendary 59 tweed 5F6-A circuit. The bassman was a combo amp in the tweed era with the 1×15″ and 4×10″ speaker configurations. From the blonde era Fender made the Bassman as a amp head and 2×12″ closed cabinet. So what does the blackface Bassman sound like? Describing tone is best done with establishing a common and well-known reference point, for example the traditional blackface AB763 amps such as the Super Reverb and Twin Reverb. The Bassman is known for its simple, pure and raw tone. It is 50w loud with power supply and output transformers sized approx. as the Super Reverb and Bandmaster. The bass channel of the AB165 and AA864 is much mellower and deeper than the normal channel of any AB763 amps since it is voiced for bass guitars. The Bassman bass channel features a deep switch that can remove the lowest frequencies, which is practical when you’re playing loud and using different speaker cabinets where you need to adjust the lower bass. The normal channel is more relevant for guitar players. The Bassman sounds “browner” than the AB763-amps, particularly the AB165 model, and it has more preamp distortion and mids when the volume is turned up. The Bassman has significantly influenced the whole guitar amp industry since it was introduced. It’s tone stack, tube configuration, preamp and power section has inspired numerous amps builders including Jim Marshall, the founder of Marshall amps, who used the Bassman tweed 5F6-A circuit in 1958-1959 as template the legendary Marshall JTM45"

4. Fender website: "The late-'50s tweed-covered Fender Bandmaster guitar amplifier combined great looks with sweet tone and powerful performance. Hailed as one of the true holy-grail amps among guitarists and collectors, vintage examples are rare and highly sought after. The new '57 Bandmaster amp now joins our prestigious Custom series, with all-tube hand-wired circuitry and premium components. We've faithfully reproduced the classic 5E7 circuit, which pumps about 26 watts through three 10" alnico-magnet speakers, and we enlisted Jensen to help create the P10R-F driver (a Fender exclusive), which is voiced for warm, sensitive response. The Bandmaster amp's harmonically rich clean tones are perfect for vintage rock, blues and country styles, and its naturally touch-sensitive overdrive tone sounds electrifying—especially when cranked up"
5. Wikipedia
6. Fenderguru.com: "The Bandmaster came with many different circuits during the blackface and silverface eras. The blackface head had a diode recifier, one normal channel and a vibrato channel with no reverb. In the silverface era the recitifier was changed from diode to tube and the vibrato channel got reverb. Hence, the name “Bandmaster Reverb”. As usual the later silverface models were modified to become cleaner and more powerful. The 70W model from 1978 with master volume and push/pull boost had a huge power transformer and big filter caps. It reminds us more of a classic 80w Twin Reverb than a Bandmaster Reverb, and it shared its circuit design with the Pro Reverb and Super Reverb at that time. A noticable difference in the vibrato channel between the early silverface Bandmaster Reverb and blackface Bandmaster is the extra gain stage in the silverface amps. This was also the difference between the first 1964 blackface AA864 Bassman and the following AB165. This gain stage was introduced as a part of the reverb recovery circuit, the V4 12AX7 to be exact, common for all the reverb amps of the blackface/silverface era. Amps with no reverb recovery stage cleaner sounding and will remain pretty clean when you turn up the volume knob above 4. The extra gain stage in the silverface Bandmaster Reverb amps contributes with tube distortion and compression in the preamp section when the amp is pushed. Not only is there more action in the preamp section, the silverface models also has more sag and looser response due to the tube rectifier. The Bandmaster Reverb head will remind you pretty much of the amps in the Pro Reverb, Super Reverb and Vibrolux Reverb where the sweet spot is to be found around 4 on the volume knob. Not all silverface amps were developed in a bad direction. Let’s study the blackface Bandmaster AB763 and Bassman AA864. They are similar in the way that both are clean sounding with just one 12ax7 tube in the preamp stage (vibrato ch in bandmaster and normal channel in bassman). The vibrato channel in the Bandmaster is even more clean than the Bassman because of the vibrato circuitry loading the signal chain and reducing the gain level in the premp section. Hence, the AA864 Bassman normal channel has more preamp “juice” and reaches the sweet spot at an earlier volume knob setting. The Bassman has a slightly bigger output transformer resulting in a firmer tone and more attack. A smaller output transformer will introduce sag and compression in the power amp section. The blackface Bandmaster is therefore ideal for those who look for a pure Fender clean sound without making ones ears bleed. The blackface and silverface Bandmaster is a big sounding amp with a flexible speaker impedance of 4 ohm, allowing anything between one and four speakers (8 ohm each) to be connected via the main and/or external speaker jack. This makes it possible to adapt to small and big stages and gigs just by configuring the speakers"

7. Scottl on The Gear Page: "The Ojai is an exact copy of Dumble #102. Robbens tan Dumble. It also requires the Dumbleator and specific capacitance cables to run to and from the Dumbleator (about 180-200pf per cable). This due to the large bright cap on the amp master. All controls are marked in silver sharpie for the exact settings of Robbens tone. The pot tapers are all 30% audio taper, except the treble control, presence, and the OD in/outs which are linear. Robben sets his mids at about 70K from ground. All my clips are recorded with the amp set both on the outside, and the trimmer on the inside, to be as close as possible to the Robben OD tone. One super important element is the correct setting of the internal gain trimmer that sets the amount of attenuation between V1 and V2. It should be between 25K and 26K to ground" Source
8. Information from the owner, forum member AustinBuddy: "The model is of a 100w 6L6 BludoDrive Ojai by Bludotone amps, using Fractal's MIMIC process. The Ojai has the same schematic as the famous "Tan" boutique amp played by Robben Ford. It pairs well with the factory Rumble 4X12 cabinet. The amp was modeled with the preamp boost (PAB) set to ON for both clean and lead channels. You can defeat the preamp boost effect on tone by switching the tonestack voicing to "Skyline", which will also reduce gain. On the Ojai there is a bright cap on the Master Volume. As you turn the MV down, it will get thinner. This makes the MV even more sensitive than usual since there’s another interaction going on. To get the most range out of this amp, experiment with Master Volume and listen how it interacts with low or high Drive settings, similar to the real amp. The breakup range/tones between is wide and dynamic and can respond to your playing dynamics, getting crunchier as you dig in and cleaner as you play lighter. The amp's Bass response should increase noticeably as you turn up the Master Volume from the default MV position.
   • For a super clean sound, use BludoOjai Clean and change to the Skyline tonestack instead of the Default. Set Drive low (below 2) and Master about 3.5, and Master Input Trim turned way down at 0.333 (it will warm up with gain/mids as you approach 1.0), Bright switch on, with Presence knob around 5.
   • At the other end of the spectrum, for endlessly sustaining any note on the Lead amp model, try Drive around 7+ and Master around 7+ with PAB on (= default tonestack). Turn up Input Trims to taste over 1 if you like. You can put a clean boost in front as well to help"

11. Cliff: "Rips my head off here. I have to turn the presence way down. Check the MV. Too high and will get muddy" Source
12. Cliff: "That "interference" is due to all the treble peaking used in the design. JCM800s have quite a bit of treble boost. When you first attack the string the note is unpitched. It's basically a brief explosion of noise. The treble boosting amplifies the upper frequencies of this noise burst which is what you hear. However, when you playing in a loud mix that treble boosting helps the sound cut. Modern designs use more carefully crafted treble boosting to retain the cut but tame some of the harshness of the attack. This is accomplished typically by putting a capacitor in parallel with the plate resistor(s) which rolls off around a few kHz. This preserves the treble boost in the upper midrange but softens the attack. I believe the SLO100 was one of the first amps to do this. You can see this in the Axe-Fx II as your Triode Freq parameters. You can soften the JCM800 attack by lowering the Triode Freq values. Most modern hi-gain designs use some form of HF rolloff like this. Another reason is that JCM800s use relatively low amounts of negative feedback (which is why they're so loud). This causes a treble boost in the power amp. Increase the Damping parameter to increase the negative feedback" Source

The second-to-last triode is associated with "Triode 1 Freq" in the advanced parameters. You can adjust this to simulate adding a cap to the plate. The other thing that helps the tone is the 220K plate resistor on the last triode. This shifts the bias point down vs. a "classic" Marshall. Unfortunately the bias points aren't exposed to the user" Source

6. Alan Phillips: "In the real world the OD2 is very very fussy on speaker choice too. The real world speakers of choice are EVM12L in a 1x12 rear ported and 2x12 with Celestion Classic Lead 80's. I found the 12L emulation did a pretty good job. Some of the others sounded so artificial with that model. Like a Rockman. Coupled with the right cab the emulated model does a good job of representing the basic tonal signature of the amp". And: "It's not a competitive model, it's a live demo of an OD2 as tweaked by me. Damn sight better than sound clips for auditioning to guys that haven't got the ability to get to a Dealer. Clearly it doesn't give you the full experience of the full amp, but is a good tonal taster. I repaired a Soldano SLO for him one day and when he came over my house to pick it up we just decided it would be a good idea to put a CA model in there. Having the actual builder involved kind of closes the loop fully. I'm happy to endorse that model because I put a lot of hours testing it and putting together a ton of technical information, fourier analysis graphs, frequency response graphs, schematics etc that would make validation of a mathematical model much easier. In reality even though the power amp and the preamp are modelled the pre-amp got the most effort. As I said in another thread, I tuned that by putting the axe in to the actual power amp of an OD2 and running that side by side with a full OD2. The final tweaks were made like that using parametric eq blocks that were hard coded in to the model. You could call that the icing on the cake and basically put the same level of tuning into the model as I do with a actual OD2. The only difference was I was using a GUI, not resistors and capacitors"

And: "Though widely believed to be a Class-A amplifier, the AC30 is in fact a class A push-pull amp with cathode bias. It utilizes a quartet of EL-84 output tubes. The high bias condition is believed by some to be the source of the amplifier's famous immediate response and "jangly" high-end, though the lack of negative feedback, minimal preamp circuit, simple low loss tone stack, and the use of cathode biasing on the output stage play at least as large a role, if not larger. It's the Celestion "Blue" speakers that are integral to the AC30, and also contribute much to the sound of the unit. The two 12" 15-watt speakers, often overdriven and at the brink of their power handling capability, provide a cutting mid-range speaker sound that is immediate and sharp and a distinction from the Marshall or Fender-style amplifier"

The Bass and Mid controls are functional and recreate the amp when set to noon. Also note that this amp suffers from extreme blocking distortion at or near maximum gain. This is common in very old designs. As it is virtually unplayable like this, the model uses a somewhat reduced level of grid conduction to lower the amount of blocking distortion and make the amp more playable at high Drive settings"
8. Cliff: "I had to make some decisions on the model and what you have is based on what I felt offered the best starting point. You have the tools in the model to mold it to your preference. Add some bright cap, increase the input trim, etc. to achieve your own personal sonic goals. Hit the boost switch or increase input trim to simulate jumping the inputs" Source
9. Fenderguru.com: "The Blackface Deluxe Amp is often misinterpreted as a Deluxe Reverb without reverb. It might seem so if you take a look at the front panel and the knob functions. But a closer study of the circuit design will reveal that the Deluxe Reverb vibrato channel has the extra gain stage (one half of the 12AX7 V4 tube) common for the Fender reverb amps. The wet reverb signal is mixed together with the dry signal which has gone through the 3.3MOhm resistor, therefore needing a gain boost before entering the phase inverter. This means one less tube in the Deluxe Amp in the preamp section that will contribute to sustaining harmonics, compression and sag. The Deluxe-Amp is therefore cleaner when played high on the volume knob. Still, the clean sound of these amps sound fairly similar goven a common EQ circuitry, phase inverter and power amp section. When the volume is pushed beyond 4-5 where the amps will differ in tone. The Deluxe will remain relatively clean, while the Deluxe Reverb breaks up in a typical blackface manner. Being a middle size Fender blackface amp the Deluxe has not been modified and experimented with so widely as other Fender amps. It’s power, clean headroom, physical size and tonal characteristics have matched the expectations of more players than any other tube or transistor guitar amp of any brand on this planet. It is said that the Deluxe Reverb is the nr 1 most used amp in recording studios. We can understand why. It is powerful enough to cut through in a band with a drummer and reaches the sweet spot at a reasonable volume. It has the typical blackface 60′s sparkling, scooped clean sound as it’s bigger brothers, just with more smooth breakup, sag and compression. The smaller brother Princeton Reverb is rolling off more top frequencies and breaks up earlier with more warmth producing a brownface type of tone. It can not really cut through with Albert Collins’ icy licks like the Deluxe"

6. Fenderguru.com: "The Deluxe Reverb 1×12″ has for decades been one of the most popular amps among all Fender amps, and its popularity is still growing as the demand for low wattage tube amps increases. The combination of size, weight and performance makes the Deluxe Reverb a true road warrior on gigs and practise. Since the year 2002 we have observed, by monitoring the amp market on US ebay, that low wattage amps have increased dramatically in popularity. Nowadays (2012) you can score a big 6L6 vintage Fender amp for the same price as a Deluxe Reverb or Princeton Reverb. We find it irrational. The PA was invented long time before that and guitar tones containing fuzz and distortion have been around since the sixties-seventies. Why has the desire for low wattage amps with 20-25 watts of tube power come up so late? Both the Deluxe Reverb (DR) and Princeton Reverb (PR) “survived” the CBS silverface periods with minor changes. Many people consider the silverface amps just as sonically good as the blackface models. Being almost a blackface amp with a new faceplate (wrong for collectors), the silverface models became popular value-for-the-money amps. Collectors hunt the blackface models and players hunt the silverface for it’s quality and price. The push/pull volume boost was installed in 1977 by CBS. The circuit was then significantly different from the blackface circuit. Hence, the price for this amp is lower than it’s predecessors. The DR is a small/medium-sized amp with an ability to deliver both sparkling clean tones and low wattage breakup at 22W with 6V6 tubes and relatively small transformers (power and output). It has found its way in to more recording studios, clubs and bars than any other Fender amp. It has met many players’ expectations. It is just powerful enough to cut through in practise in a band with a drummer and, unlike some bigger amps, it will reach its sweet spot at a reasonable volume. It has the typical blackface 60′s sparkle with a scooped clean sound just like the bigger Fender brothers, just with more smooth breakup, sag and compression. The smaller brother Princeton Reverb is rolling off more top frequencies and breaks up earlier with more warmth producing a brownface type of tone. It will not cut through the mix as easily as the stingin tone of the Deluxe Reverb"

6. Fenderguru.com: "If an alien came to earth and wanted to hear an American guitar sound, I’d play him my Twin with a set of Jensens. This was stated by a happy Twin Reverb owner on Harmonycentral.com. It could have been our own words. The Twin Reverb is the king of Fender blackface amps. Having two pairs of 6L6, the popular and traditional two-channel AB763 circuit design, a diode rectifier and enormous transformers (power & output), it offers tons of clean headroom and volume for unmiked gigs and really big stages. Where the other Fender amps break up at around 4 on the volume knob, the Twin stays clean up to almost 6 and will hold up against heavy drummers and bass players with clean notes sharp as a knife edge. This is exactly what the amp is made for, being played unmiked in in a gospel band in a 300-seat church every Sunday. It is designed not break up like the other Fender amps. You need to have your expectations set correctly to be able to appreciate the evil Twin. Warning nr 1) Weight. The big transformers and speakers makes this amp weigh around 40kgs, a burden too big for many gigging players who cannot (yet) afford a crew of roadies. Warning nr 2) Volume and clean headroom. If you want tube amp breakup and smoking tones with no pedals you will experience many fights with your band mates and club owners. Just as the other Fender amps the Twin needs to operate in its sweet spot up to sound sweet. After carrying a Twin Reverb on to the stage, the least you should deserve is to crank the bastard. Sadly, we are seldom offered the opportunity to turn the volume above 3 on a Twin Reverb. Instead we have played many nights with a thin and unpleasant tone, even worse with a sparkling, clean sounding strat. If you are one of these players, you should find some mods on this page interesting. With just a few simple tricks you can make your Twin break up earlier like the more versatile Pro Reverb 2×12 and Deluxe Reverb 1×12"
7. Cliff: "After CBS bought Fender the new engineers set out to "fix" those lousy designs with all that nasty distortion. The first of these amps were late '68 or early '69 IIRC. They increased the negative feedback, changed bias points, added MV, etc. The new designs were much cleaner and much less desirable IMO. Blackface Fenders from the mid '60s are the most desirable because they have that nice breakup. Silverface Fenders are not particularly prized and are often modded to turn them into Blackface circuits" Source

5. Bogner website: "20th Anniversary Ecstasy: we consider this model to be the new "Flagship" in the Ecstasy line with the most organic and open sound yet. Available as an option to the base model the 20th Anniversary has a plexi panel with gold background and is housed in a slightly larger head shell for an iconic and classic vintage vibe. To further celebrate our 20 year anniversary this series is offered in white tolex with a classic salt & pepper grill at no additional up charge which applies to the cabinet as well if ordered together with a head. All other color and grill options are available for the usual up charge, however the Metal Grill option is not available. The 20th Anniversary is our finest evolution of the Ecstasy line that started with the 100B, then 101B, and Classic Options. However, the 20th Anniversary model features it's own unique circuit and many refinements never before seen. In the past few years many new boutique capacitors have come on the market such as the Sozo brand which focus on replicating the vintage toneful capacitors from the 60's. These new capacitors are very expensive and mostly hand made in their construction so we were intrigued to hear how they sounded. We purchased all the available brands and meticulously went trough the entire audio signal chain of our Ecstasy circuit incorporating these vintage style capacitors into the design"

5. Bogner website: "Uberschall is the German word for Super Sonic and we designed this amp primarily for extreme, heavy and aggressive styles of music. Detuned or baritone guitars crave this amp. Also, be sure to check out the matching Uberkab 4x12 speaker cabinet below. Two versions are available, the UBERSCHALL with it's traditional clean and super high gain channels and the TWIN JET with a semi clean to hot rod gain and super high gain channel configuration. While the super high gain channels are identical there is more flexibility and control on the TWIN JET as well as a additional controls for the power amp section. We unleash mayhem with the super aggressive high gain channel with gain, bass, middle, treble, volume and presence controls. You think you've heard BASS before, no way, the UBERSCHALL can crush on demand. Even with extreme gain and volume this channel stays massively focused and resists mushing out from the heaviest right-hand attack. Power comes from a throaty EL34 output section. Go ahead, try and hide from the UBERSCHALL it will seek you out, relentlessly, while you sleep, in this life and the next... But all will soon embrace the UBERSCHALL and we will wonder how anyone tried to play standard tuning, 7-string or drop tuned guitar without it. Our UBERKAB is perfectly matched for the thunderous UBERSCHALL. This 4x12" straight front speaker cabinet features a black front speaker grill with silver piping and a combination of front loaded Celestion Vintage 30's and G12T75's wired at 16 ohms. This combination unleashes the aggressiveness of the UBERSCHALL amp, plus helps to maximize the low end and give great cutting power to the mids and highs. Our standard Bogner 4x12" cabinet, with Vintage 30's, also sounds great with the UBERSCHALL"
6. Wikipedia
7. Bogner: "One of the most unique items is our "Presence" control. It's an amazing combination of a midrange-presence control. As you sweep through its range you will notice an incredible variety of tones this one control allows. For an extremely aggressive sub-harmonic bass and scooped-midrange sound, keep the presence off or very low. A huge 3-dimensional tone can be found by running the presence around 2 o'clock. Pushing the "Presence" control to maximum will allow you to cut a sonic path through the mix by reinforcing your midrange and slightly rolling off the sub-bass. Trust us: REALLY check out the presence control to unleash the hidden secrets of the UBERSCHALL. The "Midrange" control is very interactive with all the other tone controls, you can go from a hollow scooped-mid setting to an aggressive in your face and on your throat kind of intensity. The "Bass" control allows almost a sub-harmonic low-end to be added, at high volumes be sure to keep the bass down a bit to keep your tone focused like a laser beam"

We've added a master volume that can be engaged and utilized to drive channel one into all shades from clean to soft pushed overdrive and beyond. The little secret that loyal users of the Hot Cat have known for years is that the clean channel crunches like the sounds found on vintage 70's vinyl. Channel two is a pure Class A EL34 high gain.

It is aimed at achieving the warm, tube-driven tone common in many styles of American blues and blues rock dating back to the 1950s, while remaining both portable and affordable. Fender frequently releases limited editions of the Blues Junior. All have the same electronic components [1] and specifications but have cosmetic changes and often a different speaker, at varying prices. The Fender Blues Junior is most similar to the Fender Blues Deluxe, which adds a "drive" channel, an effects loop, and uses 6L6GC output tubes for 40 watts of rated output.[2] The Fender Blues Junior was introduced after the Fender Pro Junior, but has entirely different circuitry other than EL84 output tubes rated at 15 watts"

TUBE REVERB and TUBE TREMOLO, something virtually nonexistent in today's marketplace, is just part of the picture. Includes a 12" Custom British Vintage Series BV-25m that screams TONE with body and soul; This amp has excellent breakup (wait till you hear the samples). This all new circuit is housed in a lacquered TWEED pine cab with dark Tweed panels. This amp is in its own league." And: "The idea of the Atomic Space Tone hit me when I was working on a vintage Gibson Scout guitar amp. It had Reverb, Tremolo, and 15 watts of pure rocking vintage tone power but only three preamp tubes and two EL-84 output tubes. I thought to my self - I have never seen an amp that could do so much with so little and sound surprisingly good. But I knew it could be even better. I knew something could be built revolving around my favorite little tone generator, the 6V6. I sent a note of thanks to my cohort for the inspiration for one of the best amplifiers I have ever built and the only thing I have found to equal the soul and amazing tone of the ST-6V6se but with MORE power"

6. Firmware 10 release notes: "The ODS-100 models were redone and matched to a Dumble Overdrive Special, S/N 0213. This particular amp is a 100W “HRM” version. The lead channel was matched with the preamp bypass (PAB) engaged which bypasses the input tone stack. The lead channel was also modeled with the Drive control at approximately 7.0. The Input Trim parameter can be used to increase or decrease the drive. Note that the clean channel has a bright cap on the Master Volume. This causes the tone to get brighter as the MV is reduced and vice-versa"
7. As noted in the release notes, use Input Trim to add gain to the Lead channel
8. Cliff: "The ODS100 has two drive controls, one is right at the input, the other is in the lead boost section. Since the Axe-Fx only has a single Drive control, the model has to assume one of them was set at a certain position" Source
9. Cliff: "I hate to admit it but there is something special about a real Dumble. I don't know what it is but there is something in the voicing. The various clones I have are cool and have their own thing going but they don't sound like the Dumble. Hard amp to play though. Very unforgiving but tremendous clarity" Source
10. Cliff: "They call HRM "Hot Rubber Monkey" but what it really means is "Hot Rod Marshall". The HRM Dumbles have a fixed Marshall tone stack at the output of the lead channel. This gives a little scoop to the mids." Source

7. Cliff (about the Plexi model in the Standard/Ultra): "One of the first mods people make to real 'Plexi' Marshalls is to "clip the bright cap". The bright cap varied over the years, supposedly depending on what was lying around in the shop. The model defaults to the bright cap in the circuit. If you turn off Bright you're effectively clipping the bright cap. The bright cap in Marshalls can be very bright and harsh. However, if you crank the Master you might find the extra brightness helps compensate for the power amp getting darker"
8. Cliff: "It's the way a Plexi is supposed to sound. That's due to the cathode follower. That raspiness helps it cut through in a mix. I own three of them and they are that fizzy" Source
9. Cliff: "Don't be afraid to turn the bass all the way down or the treble all the way up. Just like with the actual amp. For example, on the normal channel of a Plexi most people turn the bass way down. Otherwise it's too flubby" Source

6. Fenderguru.com: "The Princeton Reverb is the smallest blackface/silverface Fender amp with both tremolo and reverb. With a 10 inch speaker run by a 12-15W dual 6V6 amp, it delivers a true “American” Fender tone with punchy, responsive lows together with chimey highs. When it is cranked it tends to sound a bit “browner” than the bigger two-channel amps, meaning more breakup in the lower frequencies and mid-focused tone. Much of this is due to an unefficient phase inverter circuit design. Compared to many bigger Fender amps the Princeton Reverb (PR) went through the CBS/silverface periods with very little changes. Originally the Princeton Reverb came with Jensen C10N, C10r, Oxford 10L5 or Oxford 10J4. Personally we favor the vintage Jensen C10n speakers due to the huge clean tone and big bottom end caused by the large magnet and 1,5″ voice coil. A vintage 1966 Jensen C10n matches the amp and cabinet size perfectly and you get a classic, scooped fender blackface tone from a little amp. Personally we mostly play our Princeton Reverbs at volume 5-6 with a decent amount of tube amp distortion (caused by preamp, power amp, transformers, rectifier all together). The amp delivers a thick sustaining tone where single notes are clean and chords are crunchy. A 12″ speaker will push more air and give you a bigger sound with more low ends, particularly more lower mids. A 12″ can normally handle more power than a 10″ at both lower and higher frequencies. The 12″ speaker is slightly harder to drive and if you’re really into a soft touch and finger tips you’ll probably appreciate the dynamics of a 10″ more than with a 12″. An interesting effect with 12″ speakers is the “3D” sound effect. While 10″ speakers can be front directional (depending on cabinet also) there is a better spread with 12″ speakers which contributes to a better sound on stage. People will hear you better wherever they are positioned relatively to the amp. A 15″ speaker has even more spread and it will cut through skin and bone. We have never heard anyone who upgraded to a 12″ go back to 10″. The Princeton Amp is often misinterpreted as a Princeton Reverb without reverb. Just by looking at the front panel and the knob functions it might seem so. A closer study of the circuit design will reveal that the Princeton Reverb has an extra gain stage (one half of the 12AX7 V3 tube) just after the dry and the wet reverb signals are mixed. This means that there is one extra tube stage that can cause preamp gain and contribute to the tone with sustaining harmonics, compression and sag. Hence, the Princeton-Amp is cleaner than the Princeton-Reverb when the volume is pushed beyond 3-4. The volume knob is less sensitive on the Princeton Amp, and you can play them on volume 7-8 still sounding clean"

7. Cliff: "Real Rectos are bassy/fizzy beasts but that tone works great for certain genres" Source
8. Firmware 10 release notes: "All Recto models have been reworked. Note that the Orange Modern and Red Modern models have no negative feedback and therefore the Presence control is a Hi Cut control. The operation of this control is reversed as compared to the actual amp. If the amp’s Presence control is fully clockwise the corresponding setting of the model’s Hi Cut control is fully ccw. Also note that the model’s Hi Cut control has about twice the range of the actual amp so fully ccw on the amp is equal to about noon on the model. As noted in the paragraph on MIMIC, the Modern modes are highly sensitive to MV setting. Higher MV settings result in more midrange focus while lower MV settings produce a more scooped tone. It is recommended to experiment with the MV setting to achieve the desired tone while compensating for the level increase/decrease with the Level control"
9. Demo
10. Cliff: "If you are using the Modern modes be very careful with the MV. If you turn it up too high it will flub out really quick. If in doubt reduce the MV. Compensate with the Level control" Source
11. Cliff: "The Modern mode in Rectos has no negative feedback so there's a huge bass boost from the speaker impedance. Fortunately you can reduce this by reducing the LF Resonance on the Spkr tab which is something you can't do with the real amp without trying different speakers or cabinet" Source

4. Soldano website: "While setting that standard (we’ve been told) we created a modern classic. Unchanged in over twenty years, the SLO’s remarkable sound, award-winning innovative design, and flawless construction make it simply the finest amplifier money can buy. And the SLO’s tone, construction, and reliability have made it the heart and soul of many of Rock, Metal, and Electric Blues’ most creative and celebrated players. It’s because of this that you’ve been hearing the SLO 100 on your favorite records since 1987. From Clapton to Van Halen, from Warren DeMartini to Lou Reed – and from you to Mike Soldano himself, the SLO is simply the player’s choice. The SLO-100 offers two channels, Normal and Overdrive, each with independent Preamp gain and Master Volume controls. The Normal channel has a Bright switch and a Clean / Crunch gain selector switch. Bass, Middle, Treble, and Presence controls provide the tone shaping"
5. Wikipedia
6. Cliff: "The SLO-100 is the loudest amp I've ever used. It feels like there's a small nuclear explosion going off inside when ever you hit a power chord. It's a wicked amp but not something I would recommend for anything but large gigs. If you like the SLO-100 model you might want to try the Recto models too. It's not widely known but the Rectifier preamp is a derivative of the SLO-100. Some minor changes but the basic topology is identical"
7. Cliff: "I have a really good SLO-100. An original black faceplate version. Pristine condition. That amp was one of the primary amps used in the G2 modeling development. It was by studying that and a really nice JCM-800 that I finally figured out the secret to cathode follower" Source

9. Adam Cook (firmware 7.01): "Because of the no-negative feedback design of this amp the Master knob is VERY powerful when it comes to altering the tone of the amp. When you crank it up the mids get much more pronounced and you get a real warm fat singing lead tone. But it still responds incredibly well to the volume knob so when you back that down all of a sudden the highs and lows become more pronounced as it cleans up. When I saw Guthrie use this amp his "clean channel" consisted of using a volume pedal to back off the input and his full volume tone was singing high gain. You can totally do that with this amp model now" Source
10. Demo by Pete Thorn
11. Cliff: "The Badgers were MIMIC'd with power scaling at full. The knobs are a bit confusing on a Badger. The knob closest to the input jack is labeled "Gain". It is equivalent to the Drive knob in the Axe. The knob labeled Drive is the Master Volume" Source

The 45-watt Super Reverb’s medium output and stage-filling sound make it the perfect amp to crank up for club gigs or the concert stage. Features include dual 6L6 Groove Tubes output tubes, one 5AR4 rectifier tube, four 12AX7 preamp tubes, two 12AT7 tubes, four 10” 8-ohm Jensen P10R speakers with alnico magnets, dual channels (normal and vibrato), tube-driven Fender reverb, tube vibrato, two-button footswitch for reverb and vibrato on-off, black textured vinyl covering with silver grille cloth, and tilt-back legs"
5. Wikipedia
6. Fenderguru.com: "The AB763 Super Reverb is a very popular Fender amp due to the huge tone, robustness and the pure tone from the traditional blackface AB763 amp design. The AB763 design is also to be found in some silverface amps between 1967 and 1969. The later silverface circuits were changed further by CBS to become cleaner, harder and thinner sounding, specially if one compares amps at the same volume and EQ setting. If you’re into sparkling clean tones, a silverface can do the job just as well as a blackface amp. The blackfaces have more growl and a distorted, cranked tone. It is heavy to carry with the 4×10″ speakers and massive iron transformers. The height also makes it difficult to carry, making you sweat when hauling it between gigs. It’s a big sounding amp with a potential for being very loud and bassy given the right (wrong) speakers. The nature of the 4×10″ speaker configuration is a directional tone with screaming treble right forwards and backwards and unfortunately little spread. A lot of deep bass is produced by the bigt cabinet while the important mids are fairly low, a scooped tone. Many players are stupid and increase the volume to compensate for the lack of spread and mids. This will introduce even more bass and sharp treble. Playing the Super Reverb is not supposed to be easy… Despite all the difficultness with this amp there will occasionally be gigs, perhaps outdoors or at a big stage, where the amp won’t hurt anyone in a radius of 3 meters. You are allowed to turn the volume beoynd 4 where the amp comes alive. We remember these occasions as our happiest musical moments. The notes bounce off our strings and we are musically and physically connected with the amp just using the pick attack and guitar volume to roll back and switch between rythm and solo. Perhaps a transparent boost pedal to take us into David Gilmour land with sustain, harmonics and a creamy tone. You can physically feel the dynamic response from one of the best vintage Fender amps of them all. But only if you know how to tame this beast"
7. Cliff: "I modeled the Super with V1 pulled as most people pull V1 so the amp has more grunt. Turn down the MV to make it cleaner" Source
8. Cliff: "The Super Reverb model is "Diaz Modded". IOW, I pulled V1. This gives the amp a lot more gain so it's not surprising you're getting breakup at around 1.5. You can un-mod the model by turning down the MV Trim to around 0.5". Source
9. Cliff: "Remember that all the models use the "High" input (Input '1' on Fenders). If you want to mimic the "Low" input lower Input Trim" Source

It can produce 22W through 2 6v6's or 35W through 2 6L6's. The Jet 22 and 35 have a Custom Reverb-type circuit but are more basic in their features. The Jet does not include the EQ1/EQ2 switch and has a simpler feature layout than the CR V3. It offers the basic EQ settings - bass, mid & treble - and it is closer to the EQ2 or the CR Sig in voicing. Same serial effects loop as the Custom Reverb, and same all-tube spring reverb. The Jet 35 has a pull bright, mid and deep boost, as well as the bypass and lead switches availble by a "pull" pot on the front of the amp"
6. Cliff: "Yes, it's very smooth but there's this unique chirp or something that I've never heard in an amp before. When you hit the note there's this blast of high end that rapidly decays so it has an almost vocal quality. The frequency shaping is very different than most other amps" Source

To replicate the function of the Pull Shift, set the Depth to zero. Also note that the gain of these models has been increased by about two as most people set the Drive knob higher than the setting used in the original models. You can fine-tune the gain using the Input Trim parameter in the Advanced menu. Also note that the Presence control (as in the actual amp) is neutral when set to 5.00 (noon). Turning the knob CCW decreases the amount of presence and vice-versa. By comparison, most amps are only able to increase presence and the control is neutral when set to zero"

7. The graphic EQ on the real amp is positioned between the preamp and the power amp section. As such it can't be simulated exactly. See the Mother-of-all-pedal-and-effects-emulations thread for the EQ settings
8. Cliff: "The MK V is basically a compendium of previous Mesa amps. There may be minor differences in tone due to circuit layout but nothing a few tweaks to the EQ can't fix" Source
9. Cliff: "The MK IV and Triaxis models were modeled with the Lead Drive set to 5. Increasing the trim isn't exactly the same as increasing the Lead Drive but it's so close that you shouldn't hear a difference. It isn't actually where the gain is applied that makes the difference. Both gains are early in the chain and well before any significant distortion is occurring. The reason the two controls behave different is that the Gain control has a bright cap across it while the Drive control does not. There is a slight Miller frequency dependence on the Drive control but it's insignificant. Therefore... you can treat the Input Trim as the Drive contro." Source
10. Cliff: "Having owned multiple Mark IV's, multiple Triaxis's and a variety of other Boogie products, I can tell that the Mark series in general are a bitch to dial in. Once you figure them out though they are great amps. IMO, the key to a MKIV is to use the TMB to get the feel and the EQ to get the tone" Source

   • 98 (Vibro-King)
4. Fender website: "Fender introduced the Vibro-King in 1993 to great acclaim, marking a return to a great hand-wired amp tradition while including a previously unavailable selection of sought-after features. In the two decades since, guitarists and amp aficionados everywhere have prized the enduringly classic Vibro-King as one of the most touch-sensitive amps ever, with sparkling-clean shimmer at lower volumes and powerfully thick overdrive when cranked up. Fender now celebrates those two decades of great tone with the 20th Anniversary Vibro-King. Fender and Jensen collaborated on the amp's trio of warmer-sounding 10" speakers, and a finger-joined solid-pine cabinet increases resonance. Other premium features include all-tube hand-wired circuitry, custom Schumacher® transformers, and much more"
5. Cliff: "Remember that all the models use the "High" input (Input '1' on Fenders). If you want to mimic the "Low" input lower Input Trim" Source
6. Cliff: "The model is based on the custom version which has higher plate voltages which causes more overdrive on the power tubes. It’s modeled with the Fat switch on. Turning off the Fat switch reduces the gain by about 4 dB so set input trim to around 0.6"

Vibrato Lux (based on Fender Vibrolux Reverb)

1. Based on: 1963 Fender Vibrolux Reverb, blackface, 6L6, two inputs, two channels. Speakers: 2x10 (Jensen C10Q) or Oxford 1x12

   • or EVM 12L
3. Original controls (Vibrato channel): Volume, Bass, Treble, Bright switch, Reverb, Speed, Intensity
4. Fender website: "The Custom Vibrolux Reverb is more a modern interpretation of a classic Fender rather than a reissue; connoisseurs call it a “little Vibro-King.” Turn it up when you want to soar, or turn your guitar down to play clean with this super-responsive 40-watt all-tube amp. The more dynamic your style, the more you’ll love its ability to whisper or scream in response to changes in your pick attack. Features include dual 6L6 Groove Tubes output tubes, five 12AX7 preamp tubes, one 12AT7 tube, two 10” 8-ohm Jensen P10R speakers with alnico magnets, two independent channels (normal and bright), reverb and vibrato (both channels), 4-ohm external speaker jack, two-button footswitch and tilt-back legs"
5. Fenderguru.com: "The 35w blackface Vibrolux Reverb (VR) is the smallest member of the blackface/silverface 6L6 Fender amp family. Its strength lies in the sweetness and early breakup caused by the smaller transformers than the Super Reverb, Vibroverb and Pro Reverb. The Vibrolux is quite similar to the Pro Reverb 2×12″ except for the smaller speakers and a smaller power transformer delivering less 6L6 plate voltage. Hence, less clean headroom. 10″s provide a more scooped, responsive, punchy and sparkling sound than 12 inch speakers. The 12″s are fuller, warmer, has more mids and a more three-dimensional tonal spread. Like all silverface amps, the Vibrolux Reverb was modified in the CBS periods to increase the clean headroom. The Vibrolux Reverb has become a very popular amp since The ToneQuest Report published the article “Under 40 Watt of Whoop Ass“, awarding the VR as the most preferred low wattage Fender amp"

6. Fenderguru.com: "Stevie Ray Vaughan’s musical influence has made the Fender Vibroverb the most sought after and hyped of all Fender amps. He played many other amps too, Super Reverb, Dumble and Marshalls. In studio he used dozens of amps that were thrown at him. For some reason the Vibroverb has become the most famous and is now widely associated with his signature tone (though you can reproduce his tone with most Fender amps with the right speakers). On the vintage amp market on US eBay the blackface Vibroverb sells for three to four times as much as the price for other 6L6 Fender amps, sometimes even more than the legendary 4×10″ narrow panel tweed Bassman. Since Fender did not continue the Vibroverb after the CBS takeover in 1965, most likely because players didn’t desire 1×15″ amps at that time, there are only a few blackface Vibroverb amps out there. Given the hype and popularity, these few Vibroverbs are extremly valuable and collectable. So, what is so special with the Vibroverb? First, the 15″ speaker sets it apart from most guitar amps. While most guitar amps have multiple 10″ and 12″ speakers the Vibroverb came with one big Jensen C15n or JBLd130f, the last one with a aluminium dust cap that can be hard to tame. Otherwise the blackface Vibroverb is very similar to the other blackface and silverface AB763 Fender amps. In fact, there aren’t any different features or technical improvements in the Vibroverb that justifies its popularity. It’s all about emotions. But that’s what music is all about; emotions. The Vibroverb belongs to the 6L6 Fender family. It is powerful and loud, but in a different way than the 10″ and 12″-amps. The Vibroverb did not sell very well in 64 and 65. Players probably thought the amp was suited for bass amps, we’re not sure. The Vibroverb did score among steel guitar players at the time. The 15″ speakers are firm in the bass and have lots of sparkle but most importantly, they have an enormous spread carrying the lower mids to anyone on stage. Mid frequencies is exactly what you need on stage in an electrical band. The mids will blend in nicely with the bass, drums, piano and horns. It will not interfer with the bass like a 4×10″ setup does. Of course this is a matter of taste, but a guitar tone with strong mids will contribute to a rich overall melodic footprint in an electrical band"

6. Cliff: "The Trainwreck depends on power amp distortion. The OT has a high impedance which causes the power tubes to enter clipping early. I would not recommend using that model as preamp"
