Hadn't given it a lot of in-depth thought, just had the general idea. I thought someone else must have had the same idea, I just haven't run across it. Is the shredmaster based at all on the Rat?What’re you thinking? A Bax Rat? A pre-gain bass control, post-clipping mid-contour, and a low pass after the output buffer? Or something like a shredmaster with a pre-recovery FMV and a post-recovery mid-contour?
If you're into stripboard at all I'd trust this one: ProCo / Fuzzdog 3-Band Rat
