I built a fuzzface using the creepyfingers fuzzface, removed the 8k2 resistor which was replaced by a b20k pot, and sent into the BMP tonestack 2/LPB-1 booster from the site but I can't get it to bias correctly. I originally had it all on 1 board, but I couldn't get any output, so I have 2 board now which corrected that problem, but now it won't bias properly. At any setting, even 8.2k it's just super gated and really nasty sounding.I've changed transistors, checked the pinouts but they're right. What can I do to get the bias right, or could there be something else wrong?
