Pictures of some of the amps

Axe-Fx name	Details of model
TUBE PRE	= STUDIO TUBE PREAMP Completely neutral, low-gain tube pre-amp simulation. Useful for warming up vocals and other instruments as well as direct guitar sounds Cabinet suggestion: n/a
JAZZ	= ROLAND JAZZ CHORUS JC-120 Based on a Japanese 2x12 solid-state combo amp with built-in stereo chorus. With essentially no tone shaping this amp has a warm, midrange-thick sound that is good for jazz and fingerstyle. With the Axe-Fx’s powerful tone controls you can tweak this type to get shimmering rhythm tones as well Cabinet suggestion: none. Alternative: Red Wirez JC-120 Original controls: Volume, Treble, Middle, Bass Original manual
BROWNFACE	= FENDER VIBROVERB Based on a classic American 40-watt tube amp with built-in vibrato. Great for gutsy blues, this type breaks up nicely, especially when the Master is cranked. The original had no Mid or Presence so set these to ‘0’ for classic tone Cabinet suggestion: 1x10 Gold. Alternative: Red Wirez Fender Dual Showman Original controls (Normal channel): Volume, Treble, Bass. Later models: Bright switch. Normal/Bright channel. For authentic clean tone: crank the Master, Drive at 3.50. For more crunch turn up Drive Fender tips in the Wiki Wikipedia Fender Forum, The Fender Forum, FenderTalk, Fender
59 BASSGUY (formerly: BLUES)	= FENDER BASSMAN A low-to-medium gain sound great for blues. Based on a classic bass amplifier with four 10” speakers, it didn’t work so well for bass but guitar players quickly discovered it made a great blues amp. Try a treble booster in front for screaming blues work a la Albert Collins or Albert King Cabinet suggestion: 4x10 Bass. Alternative: Red Wirez Bassman Original controls: Volume, Presence, Bass, Middle, Treble. Normal/Bright channel For authentic tone: crank the Master, Drive at 3.50 Try with a Treble Booster Drive block Fender tips in the Wiki Wikipedia Fender Forum, The Fender Forum, FenderTalk, Fender
DELUXE VERB (formerly: TWEED)	= FENDER DELUXE REVERB (AB763) Based on the classic 1965 “Blackface” 1x12 combo amplifier. This amp features two 6V6 power tubes and has a great chimey tone. Turn the Drive and Master up and the amp starts to get a nice overdriven breakup The former name "Tweed" and description didn't match with the modeled amp. The name was changed to Deluxe Verb in firmware 9.01 and the amp was remodeled Cabinet suggestion: 1x12 or 2x12 Black, 1x2 Tweed or 2x12 Tweed. Alternative: Red Wirez Fender Twin or Tweed Original controls: Volume, Bass, Treble For authentic tone: crank the Master, Drive at 3.50, Mid at 6.8 Fender tips in the Wiki Wikipedia Fender Forum, The Fender Forum, FenderTalk, Fender
DOUBLE VERB (formerly: BLACKFACE)	= FENDER TWIN REVERB Based on a popular, 100-watt American tube amp with two 12” speakers. This simulation captures the Normal Channel. Very similar to the Brownface model but a little more mellow. The tone-stack is also slightly different giving it just a bit different voicing Cabinet suggestion: 1x12 or 2x12 Black. Alternative: Red Wirez Fender Twin Original controls (Normal channel): Volume, Bass, Middle, Treble. Bright switch (works with Drive below 6) For authentic tone: crank the Master, Drive at 3.50 Reference clip Fender tips in the Wiki Wikipedia Fender Forum, The Fender Forum, FenderTalk, Fender
CLASS A	= VOX AC30 A medium-gain emulation based on an early British tube amplifier. This type does not have the high-frequency emphasis like the American types and therefore has a darker sound. Try a treble boost in front for a snarling British “opera-rock” sound. This amp is notable in that it has no negative feedback around the power-amp and hence has a gritty character and less high-frequency response Cabinet suggestion: 1x12 or 2x12 Brit. Alternative: Red Wirez Vox, Red Wirez Blue, Ownhammer Blue Original controls: Cut, Volume. The original amp didn't have Bass, Middle and Treble controls, so leave them at noon and use Presence (= Cut) instead Cliff: "An AC30 has no power amp feedback so it doesn't have presence or depth controls. It has a "Cut" control which is basically an adjustable snubber on the phase inverter. The Presence control becomes the Cut control. To duplicate the amp you would only adjust the Presence negative but the model lets you boost as well if you adjust Presence positive. The Depth control won't do anything so it doesn't matter where you set it. If the Damping (Damp) is zero the Depth control is disabled and Damp defaults to zero for that amp model" For authentic tone: crank the Master, keep Drive low, keep the tone controls at noon, use Presence to cut the treble Try with a Tonebender or Treble Booster Drive block. Try with the Plexi tonestack. Or try the AC30TB tone stack (Bright on) Wikipedia Vox forum
TOP BOOST	= VOX AC30TBX TOPBOOST Based on the “Top Boost Mod” version of the Class A. The public yearned for a brighter amp and the designers responded by adding a treble boost circuit. At first this circuit was a retrofit but then included as standard. Our simulation captures the boosted high-frequency response and slightly reduced bass response of the original Cabinet suggestion: 1x12 or 2x12 Brit. Or use (or combine with) Marshall greenbacks (4x12 20w or 25w). Alternative: Red Wirez Vox and Marshall greenbacks, Ownhammer Blue and greenbacks Original controls: Volume, Cut (= Presence control), Bass, Treble For authentic tone: crank the Master, set Drive to taste, Mid at noon. Use Presence only to cut the high frequencies (left of noon) Cliff: "An AC30 has no power amp feedback so it doesn't have presence or depth controls. It has a "Cut" control which is basically an adjustable snubber on the phase inverter. The Presence control becomes the Cut control. To duplicate the amp you would only adjust the Presence negative but the model lets you boost as well if you adjust Presence positive. The Depth control won't do anything so it doesn't matter where you set it. If the Damping (Damp) is zero the Depth control is disabled and Damp defaults to zero for that amp model" Try boosting the input signal, for example with a Tape Drive or FET Boost Drive block Another approach to get a good Topboost tone: use the Class A sim, set its tonestack to AC30TB, switch on Bright (source: Scott Peterson) Wikipedia Vox forum
PLEXI 1	= MARSHALL SUPER LEAD (MODEL 1959 a.k.a. PLEXI) Based on a classic British amp, the Plexi is great for crunchy rhythm work. The original was basically a copy of the 4x10 bass amp (see Blues type above) that guitar players adopted but with EL34 output tubes and other British components. Despite being essentially a copy it had a unique voice all its own. It has somewhat low preamp gain and works best with the Master and Drive both set fairly high Cabinet suggestion: 4x12 20w or 25w, 4x12 Green. Alternative: Red Wirez Marshall greenbacks, Ownhammer greenbacks Original controls: Volume, Bass, Middle, Treble. Presence on later models. Bright (Lead channel only) Crank the Master, set Drive high. Experiment with higher Sag settings Because the bright cap (Lead channel) is very large, the Bright switch has a great impact on the amount of gain. Source Cliff: "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 the bright off you're effectively clipping the bright cap. With 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." Wiki: Bright switch Wikipedia MarshallForum
BRIT 800	= MARSHALL JCM800 (MODEL 2204) The successor to the Plexi type was the vaunted 800 series lead amplifier. Many 80’s rock hits were born using this amp and we’ve captured its tone and put it into a neat little package. This amp had EL34 output tubes, some treble peaking on the input and a little more gain than the Plexi. Like the Plexi type it likes having the Master cranked. At low Master settings the amp can be brittle but bring the Master up and the true tone of this beast comes out. Try it with any of the 4x12 cabinet types for classic rock and metal tones. Try a drive block in front for more snarl Cabinet suggestion: 4x12 V30, 4x12 20w or 25w. Alternative: Red Wirez Marshall, Ownhammer Original controls: Gain, Bass, Middle, Treble, Presence, Volume For authentic tone: experiment with medium to high Master volume levels The bright cap on the original (Lead channel) is tied to the pre-amp gain setting (Drive). If the amp is too bright on low Drive setings, switch off Bright Try with a TS808 or Tube Drive block, set the Drive block to zero Drive and full Level Wikipedia MarshallForum
BRIT 900	= MARSHALL JCM900 The successor to the 800 series was the 900 series. This amp had basically the same power amp but a new preamp with more tone shaping, more gain, and a solid-state clipping circuit that gave it a raspier sound. This amp was designed to get more of its distortion from the preamp than the earlier models but you can still keep the drive low and turn up the Master for more power amp distortion Cabinet suggestion: 4x12 V30, 4x12 75w, 4x12 T75, 4x12 25w. Alternative: Red Wirez Marshall, Ownhammer Original controls: Gain, Bass, Middle, Treble, Presence, Volume The bright cap on the original (Lead channel) is tied to the pre-amp gain setting (Drive). If the amp is too bright on low Drive setings, switch off Bright Experiment with medium to high Master Volume levels Try with a TS808 or Tube Drive block. Set the Drive block to zero Drive and full Level Wikipedia MarshallForum
BROWN	= EDDIE VAN HALEN'S MODDED MARSHALL Based on a modified British style head with plenty of gain and lots of mids and highs. This type captures the sound of Eddie’s early work. Crank the Master and bring the drive up until you reach sonic nirvana Cabinet suggestion: 4x12 20w or 25w, 4x12 Green. Alternative: Red Wirez Marshall greenbacks, Ownhammer greenbacks Original controls: Volume, Bass, Middle, Treble. Bright (Lead channel) For authentic tone: crank the Master Volume, turn up Drive. Or use the factory preset The Brown Sound Because the bright cap (Lead channel) is very large, the Bright switch has a great impact on the amount of gain Tip in the Wiki about the Bright switch Wikipedia MarshallForum
BOUTIQUE 1 BOUTIQUE 2	= MATCHLESS CHIEFTAIN: RHYTHM / LEAD BOUTIQUE 1: A medium-gain, thick, yet crisp, sound with a fair amount of power amp breakup. Based on a now-defunct amplifier that was renowned for its liquid tone and endless sustain. This amp had very unique tone controls and as a result a distinctive voice with a bell- like quality. The preamp gain is fairly low so crank the Master to get that gutsy crunch. Good for rhythm work in a sparse situation where fullness of tone is required BOUTIQUE 2: Same as Boutique 1 but with more gain and a bit more high-frequency emphasis. The lead version of Boutique 1 Cabinet suggestion: 2x12 Boutique. Alternative: Red Wirez Matchless Based on a Vox circuit Original controls: Volume, Master Volume, Bass, Treble, Brilliance (Presence). No Mids Keep Mid at noon. Turn up the Master Volume for crunchy leads Tips in the Wiki Original manual Wikipedia
HIPOWER 1 HIPOWER 2	= HIWATT DR103: NORMAL / BRILLIANT CHANNEL HIPOWER 1: A medium-gain, full sound based on a famous “High Wattage” amp. These amps had a unique tone-stack and industrial quality output transformers with tremendous frequency response. Chimey with a bit of power amp breakup. Plug in your Tele and crank out some Baba O'Reilly HIPOWER 1: Like HiPower I but using the “Brilliant” channel Cabinet suggestion: none. Alternative: Red Wirez Fane Original controls: Volume, Master, Bass, Middle, Treble and Presence Dialing in the Hiwatt Wikipedia
USA CLEAN	= MESA BOOGIE MKIV, CLEAN RHYTHM 1 CHANNEL A somewhat neutral clean sound that can pushed into gentle clipping. Based on a classic California amp’s clean channel this type has a full tone with a gentle midrange dip. The power amp is punchy and clean but can be driven into light distortion if desired. Sounds best with the drive turned up fairly high Cabinet suggestion: 4x12 Cali. Alternative: Red Wirez Mesa The clean channel is based upon a Fender circuit Turn up Drive, keep Master Volume low (f.e. 3.50) Original controls: Gain, Volume, Treble, Mid, Bass, Presence. Bright switch. Graphic Equalizer not modeled John Petrucci's settings Original manual MKIV: detailed descriptions of the controls and sample settings Tips in the Wiki Wikipedia Grailtone
USA RHY 1 USA RHY 2	= MESA BOOGIE MKIV, CRUNCH RHYTHM 2 CHANNEL: FAT SWITCH NOT ACTIVE / ACTIVE USA RHY 1: Crunchy California rhythm sound. Effective for solo use too with the gain turned up USA RHY 2: Similar to USA Rhy 1 but with the “mid-boost” engaged. This effectively removes the midrange dip from the tone stack and gives a more focused sound and a bit more gain Cabinet suggestion: 4x12 Cali. Alternative: Red Wirez Mesa Original controls: Gain, Volume, Treble, Mid (without/with boost), Bass, Presence. No Bright switch. Graphic Equalizer not modeled Turn up Drive, keep Master Volume low (f.e. 3.50) John Petrucci's settings Original manual MKIV: detailed descriptions of the controls and sample settings Tips in the Wiki Wikipedia Grailtone forum
USA LEAD 1 USA LEAD 2	= MESA BOOGIE MKIV Lead: Treble Shift NO / YES USA LEAD 1: A tight, focused, hi-gain sound great for fusion and rock leads. Based on a modern Californian lead amp that set the standard for hi-gain lead tones. With the tone-stack before the preamp tubes this type has a more liquid response than the British types where the tone-stack is after the preamp. For the classic California lead sound turn the drive up and back of the Master a bit so that most of the distortion is coming from the preamp USA LEAD 2: Similar to USA Lead I but with the “treble shift” engaged. This shifts the response of the treble control lower and gives a slightly different character to the tone. There is also a “treble peaker” on the input stage which slightly boosts the high frequencies giving this type a little more cut Cabinet suggestion: 4x12 Cali. Alternative: Red Wirez Mesa Original controls: Gain/Drive, Treble, Mid, Bass, Presence (without/with treble shift). Bright switch (use for lower volume levels). Graphic Equalizer not modeled Treble Shift: this shifts the range of the Presence control to higher frequencies on the original amp, it influences the Treble control. In LEAD 1 Treble Shift is off, which works well for recording. In LEAD 2 Treble Shift is switched on, which works well within a band context, but can generate squealing and noise at high volume or gain levels Turn up Drive, keep Master Volume low (f.e. 3.50) John Petrucci's settings Original manual MKIV: detailed descriptions of the controls and sample settings Tips in the Wiki Wikipedia Grailtone forum
RECTO ORANGE RECTO RED	= MESA BOOGIE 2-CHANNEL DUAL RECTIFIER (OLD, SMALL LOGO): VINTAGE ORANGE CHANNEL (RHYTHM) / MODERN RED CHANNEL (LEAD) -- The names and models changed from Recto 1 into Recto Orange and Recto 2 into Recto Red in 7.03, in firmware 7.03. The manual still lists Recto 1 and 2 Cabinet suggestion: 4x12 Recto1 or Recto2. Alternative: Red Wirez Mesa Original controls: Master, Presence, Bass, Mid, Treble, Gain. No Bright switch Turn up Drive, keep Master Volume low (f.e. 3.50) Recto Red Defaults to no Damping, can be turned up Cliff: "None of the Recto models in the Axe-Fx have the post tone-stack bass boost. If you want to replicate the behavior of a Single Rectifier you need to put an 11 dB bass boost after the preamp model. The Axe-Fx models are based on the Dual Rectifier modes with the bass boost switch off. Single Rectifiers engage the bass boost switch automatically in channel 2" To mimick the bass boost, use a PEQ or low shelf Filter after the Amp block to boost bass by 11 dB at around 120Hz. Original manual: detailed descriptions of the controls and sample settings Video demo Wikipedia Grailtone forum
SOLO 100	= SOLDANO SUPER LEAD OVERDRIVE (SLO-100) Based on a high-gain hot-rod with a chrome chassis, this amp is noted for its snarling lead sound. Also great for aggressive rhythm work, this type “chugs” nicely without getting muddy. Pair it with one of the 4x12 cabinet simulations for modern rock tones The Axe-Fx models the Overdrive channel Cabinet suggestion: greenbacks (4x12 20w or 25w, 4x12 green), G12H30 (4x12 30w), 4x12 Cali, EVL12. Alternative: Red Wirez Soldano (Eminence Legend), G12H30 or EVM12L Original controls: Gain, Bass, Middle, Treble, Master, Presence. Bright switch (on the original amp only for Normal Channel) Cliff: "The SLO100 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 SLO100. Some minor changes but the basic topology is identical." Keep the Master volume low (f.e. 3.50). It's a very bright amp, keep Presence and Treble low Original manual Soldano forum Wikipedia
SPEC OD1 SPEC OD2	= DUMBLE OVERDRIVE SPECIAL: CLEAN / LEAD SPEC OD1: Based on a coveted but rare lead head that was made famous by Larry Carlton and others. Another amp with a very strange tone-stack, this amp has a singing voice and is great for modern blues/fusion work. This is the clean channel SPEC OD2: The overdrive channel of the above Cabinet suggestion: 2x12 Custom Original controls: Master, Bass, Middle, Treble. Bright switch Wikipedia
EURO BLUE EURO RED	= 20TH ANN. BOGNER ECSTASY (XTC): BLUE / RED CHANNEL EURO BLUE: Based on a German high-gain amp, these amps pay homage to the British amps but with lots more gain and more high-frequency emphasis. This type simulates the overdrive channel with the boost and “structure” switches off. Note: the description in the manual refers to the amp sim before firmware 9.0. In firmware 9.0 this amp sim was modeled after the Bogner XTC 20th Anniversay Blue channel EURO RED: As above but with the boost and structure switches on. This one has lots of gain and plenty of low-end chunk along with a crispy top-end. Great for modern metal. But: the description in the manual refers to the amp sim before firmware 9.0. In firmware 9.0 this amp sim was modeled after the Bogner XTC 20th Anniversary Red Channel In firmware 10.x the names have been changed from Euro 1 to Euro Blue, and from Euro 2 to Euro red Cabinet suggestion: 4x12 German. Alternative: Red Wirez Bogner Original controls: Gain, Bass, Middle, Treble, Volume, Presence. Bright switch Euro Blue: try it with the Amp Boost on Both models are quite dark, use Bright or a lot of Presence Quote Cliff: "My actual XTC has a Log10 pot for the treble which is an odd choice. Treble pots are usually linear and the Axe-Fx model uses a linear pot. The problem with a log-taper pot is that the treble does almost nothing for the first 50%. So you can't use your eyes if you want to copy the tone. This is the case with several of the amp models. In these cases the taper used on the real amp is what I would call "a less than optimum" choice. I think in many cases the designer simply doesn't realize the affect the taper has on the locus. So, if I deemed the choice of taper to be "incorrect" the model uses the correct taper. The Bogner models fall into this category. The choice of a Log10 pot for the treble pot doesn't make sense so the model uses a linear taper which gives a smooth locus" Original manual 20th Ann. specifications Sample settings Sound clips Bogner Amp Forum Wikipedia
UKGC30	= LANEY GC30V Based on a great British amp introduced in the 90’s this amp is a strange marriage of a USA style pre-distortion tone-stack, British voicing and a Class A power amp. Best for blues and lower-gain rock leads, has nice sustain qualities. Can get muddy at high drive levels, decrease the bass to compensate Cabinet suggestion: none Based upon the Vox AC30 Original controls: Drive, Bass, Middle, Treble, Volume. No Bright Original manual
BUTTERY	= BUDDA TWINMASTER Loosely based on an 18-watt amp that gained notoriety during the late 90’s. This type is a low-gain amp that relies mostly on power amplifier distortion. Try a drive in front for smooth lead sounds Cabinet suggestion: greenbacks (4x12 20w or 25w), 4x12 30w or something that resembles Eminence Legends Original controls: Bass, Treble, Volume. Bright cap on the Volume control (Bright switch) Turn up the Master volume, use Drive for volume and gain, turn down Bass Try with a Drive block Wikipedia Budda Forum Original manual

EURO UBER	= BOGNER UBERSCHALL, HIGH-GAIN CHANNEL Based on the aggressive "High Gain" channel of a 120W head, this model is reminiscent of an 800, modded for heavier, grinding lows and what some call insane gain Cabinet suggestion: simulate a Bogner Uberkab by using a stereo cab or dual cabs with 4x12 German and 4x12 75w. Alternative: Red Wirez Bogner Uberkab Original controls: Volume, Presence, Treble, Middle, Bass, Gain Keep the Master volume low. Start with tone controls at 1 o'clock (original amp settings) Reworked in firmware 10.x Bogner manual: "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" Bogner Twinjet model manual: "The TWIN JET features the original high gain channel with the exception that the presence control which works in the power amp circuit on the regular Uberschall is now in the pre amp circuit which gives you an additional control to shape the sound. Reason is, the TWIN JET has a global master depth and presence control. These affect both channels and will give you control over the overall bass response and presence. Start at 10 to 11 o'clock on the presence and adjust careful to your taste. The depth control is great to give a fuller sound at lower volumes, for higher volumes it will add massive bass and might cover up the rest of the frequencies, best to keep it low but adjust to your taste."

CAROLANN OD2	= CAROLANN OD-2R, OVERDRIVE CHANNEL Based on the celebrated OD2 from CarolAnn Amplifiers as designed by the highly respected Alan Phillips Introduced in 9.01, improved in 9.03 (collaberation with the designer of Carol-Ann amps) Cabinet suggestion: EV-12 of something that sounds like a Celestion Lead 80. Alternative: Red Wirez EVM Quote 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 in to the model as I do with a actual OD2. The only difference was I was using a GUI, not resistors and capacitors."
