It would be great if, after profiling, a sperate step could be performed to profile the tone stack.
The procedure might go something like this:
1. a test signal (pink noise?) would be injected into the real amp
2. the user would be prompted to turn each tone knob from min to max then back to zero, confirming each completed tone knob by button press.
This should allow the frequency center, Q, and perhaps even interaction to be determined and used to provide more realistic duplication of the amps tone stack. This could be stored as a tone stack just like cabs.
