If you're into stripboard at all I'd trust this one: ProCo / Fuzzdog 3-Band 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?

I've not seen any such specific Rat projects like that. But you can use one of the many Rat Analysis web pages (like Electro-Smash, ) to sort out where the tone stay is and replace it with something like the GuitarPCB "Tone TwEQ", the PedalPCB "Cold Turkey" or"Equilux Mini Equalizer" to get three active bands of EQ.

Thanks guys, this is good information.
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?

As far as PPCB options go, it'd be a cinch to take the normal muroidea/rat board and remove/jumper the filter; either delete the output or swap it for an internal trim; then run the output of that into the input of the tone job board. That'd give you a 3-band rat. You could probably play with the duncan TSC baxandall EQ values and make the treble control on the tone job behave the same as the filter control on a rat moving ccw from 12:00.
I built Blower Box clone with bass/treble and it's great. It can get very fuzzy and heavy.

The Dunwich Volt Thrower adds clipping options (There's another version with a mid control, which I'd like to see):

If you have a Rat already built, I'd look at those pedal schematics, including the Fuzzdog, and take Cybercow's and mdc's advice about splicing in an EQ. I used one of those Tone TwEQ boards on a DOD250
That Ratsaw is interesting. If HM-2 chainsaw isn't your thing, you can change the values of the three active controls to whatever frequencies you want.

Pepperbox (Volt Thrower)
Not just another rat ... it's what Dunwich did with the rat circuit --> Volt Thrower ! PCB is from Effects Layout. So, we have a biploar power supply, two band EQ, 6 clipping options and a gain recovery stage built around another LM308, although I subbed in an OP07 for that stage. But thanks to...
