No tone matching!! I'm using the same settings on the real amp vs USA Lead. It is also a nice showcase of how accurate my IR capture method is as this is also a real cab mic'ed up vs ML Sound Lab IR capture method.
As you can probably tell it's now my Global Amp 1 on the Axe-Fx. All I had to do was to set the low resonance frequency to 106hz so it matches the Traditional 4x12 Mesa cab low res freq and the master level absolutely needs to be at 4. Not 5 and not 3 but 4 as I demonstrated in that video. Other than that I believe the amp sim should work just like the real thing. The real GEQ doesn't have any set values but it's supposedly +-12dB just like the Mark series GEQ in the Axe-Fx amp block. However I noticed that at least the 240hz knob on the real amp doesn't really shape the curve of the amp that much so I had to pull that one down just a little bit more on the Axe-Fx amp sim. Remember that I didn't touch any of the advanced parameters to get the Axe-Fx USA Lead sound almost identical to my Mark IV which actually has EL34 tubes in the outer sockets and 6L6GC tubes in the inner sockets.
The point of this video was to prove that the modeling quality on the Axe-Fx has reached amazing accuracy. This is not only necessarily Quantum hype. I think I could've gotten similar results with firmwares before this since the Axe-Fx has always been really good.
However I know people will be asking for the preset so here are the screenshots for the amp block:
Here's a link to those IRs and I used the Alloy IR for this demonstration and on the EP as well: http://forum.fractalaudio.com/axe-f...ound-lab-irs-clark-kent-job-generation-y.html
I'd love to hear some clips on how this preset works for you guys. That's a lot of gain! Lower the input drive to your taste. Fight the urge to try and raise that bass knob.
