Death By Audio Red/Blue Card Fuzz

With lots of help and footwork by AlexS, we managed to trace Oliver Ackermann's red business card PCB which turned out to be a noisy fuzz monster. Gain, Resonance and Filter controls is very interactive and you can dail in gated fuzz, oscillations and bizarre lo-fi filtered fuzz.

First up, schematic.

And a verified layout.

PUE Sustain Filter

A great sounding Big Muff variant from Poland dating from the early 1980's. Original has a buffer stage after the tonestack and no volume control. I did a stock layout and a modified layout with a normal recovery stage and volume control. Can't find much information on the stock BC622 transistors but any medium high gain silicon works fine.
