I just built a Big Muff few minutes ago. Unfortunately, I haven't tested it yet loud enough to scrutinize the sound because it's wee hours here. I know it's working, I tried it at low volume level.

Just want to know where can I put a drive/gain control in a Big Muff? Would that only be a variable resistor? What value?

Thanks for any help :wink:

The BMP already has a gain/drive control.  It's named Sustain.

Eh... :?  Just as what I've thought. I could have figured it out if only I can crank up my amp and take a good test of this fuzz.

Thanks anyway :wink:
