Most any EQ will allow you to configure the knobs to a preset. It seems the point of the OP may be to replicate the Peavey? I didn't search for specs on that, but if you have those in hand you can assign them as defaults to the EQ of your choice.
Also, companies themselves are pretty open to share such. I had asked Carvin about possibly using EQ on an amp sim to replicate my 212, and they sent me back the tech specs/performance of the entire guts of the amp (sorta shocked me, but I truly love those guys). The answer to my specific intent was a "no" short of programming an amp sim from scratch; but as far as the EQ knobs/sliders on the face of the amp, they are "set in stone."
