Hi Cliff.FractalAudio said:A Mesa power section is typically clean enough that putting the EQ before it doesn't sound very different than putting the EQ after it. You can replicate the sound of the MK IV EQ using the Para EQ block AFTER the amp block. I don't have the actual values at hand but it can be done and sounds virtually identical.
I know you're dead set against incorporating some sort of pre-power-amp-sim GEQ within the Amp Block for whatever reasons you have.
But maybe you'd consider adding a single parameter akin to the Triaxis' Dynamic Voice control which was designed to replicate the classic V-shape of their 5-band GEQs at increasingly more dramatic levels of mid-scoop-plus-hi/low-boost as Dynamic Voice is turned up.
[I actually hated the Dynamic Voice control on my Triaxis and never used it. It had a way of sucking all the warmth out of the tone, but that probably had more to do with their implementation of it electronically.]
Just a thought.
This might help stop threads like this from emerging from time to time, and it might even be a good addition to the Amp Block parameters in general.
