Tools you will need:
A short white noise clip: white.wav
Any good parametric EQ: Electri-Q Posihfopit ED
Any good spectrum analyzer: Voxengo Span
Loop the white noise clip in your DAW.
Bypass your ampsim's preamp and poweramp (if it allows you to do that) or set it to its clean channel and 100% neutral EQ.
Place your parametric EQ after the ampsim.
Pan the unaffected signal 100% left and the ampsimmed signal 100% right.
Put the analyzer on the master channel and set it to show you both left and right channels.
Match volumes.
Match the ampsim signal spectrum as close to the white noise as possible (don't bother with extreme highs and lows).
Save a preset in your EQ.

Works nice enough with Revalver mk2 cab sim.
