About 9 years ago I came across a circuit diagram and instructions to build a superfuzz bigmuff pedal (not even a stompbox, just a cheap effects filter). It was on, or linked from, an old Mudhoney website, and authored by someone in the band (maybe Steve Turner?).

I can't find the page anywhere on the web, but would love to find those instructions and try my hand at building one. Did any of you good folks ever come across this, or something similar?
