Features

Added in firmware 6. It This allows sampling a reference tone “fingerprint” and matching the user’s tone to that sound.

IR export and sharing

The sampled data in the Tone Match block can be converted into an user cabinet IR.

Tone matching real amps

• Cliff (about matching the amp models in firmware 6): "The speaker was not part of the equation. The benefit to this technique is that the cabinet is completely separated. "Profiling" lumps the speaker IR with the amplifier output IR since linear functions are not separable. That's why those products don't work well when you try to run into a power amp and conventional guitar cab. You don't really want to use a load box though, if you can help it. A real speaker is a much more realistic load. All you need is a DI box that can handle speaker level signals. You don't even really need a DI box. All you need is a resistive divider to knock the voltage down to line level. I have a simple little box that just has some resistors and a pot to reduce the level which I then send to Input 2."

• Cliff: "There is NO substitute for shooting an IR of the cab. IMO, this is the single most important thing you can do. Everything else is attempting to learn the cab IR through an indirect method and then you have inseparability. If you shoot the IR then do a Tone Match you can change the cab after or do another IR with a different mic or mic position and your matching data is still valid." Source
• Cliff: "Matching an amp is way easier than matching a recording. I do this every day. The trick is feeding the same signal to the amp and the amp block at the same time. The worst way to match an amp is to record it and then try to match it via a recording. The best way is to use a y-cable and send the same signal to the amp and the model.

Another approach (which is what I do) is to use Output 2 and send that to the amp. You can then send either the signal from the guitar or an analytic signal from the synth block as the stimulus waveform. Pink or white noise works great as do certain types of frequency sweeps (but these are more challenging to program). Source

• Cliff: "What *I* do is the following: Plug guitar into Axe-Fx. Route input to both amp and fx loop. Connect Output 2 to amp. Connect mic pre t Input 2. Turn Out 2 Level knob to full. Start capture on BOTH reference and user. Play a bunch of chords up and down the neck. Press Enter. Done. Another technique is to insert a synth block before the amp/fx loop and use test tones instead. Pink noise works well. I also have a "mathematical" set of six swept triangle waves that also works well. You need two synth blocks to do this."Source
