Guyatone FZ-2000 FuzzVerified
Based on the Guyatone FZ-2000 Fuzz
From the post
A pretty cool design, this. A FET booster that slams a FET Fuzz Face with hard clipping LEDs. All 10k Source resistors is replaced with trimpots for yeasy biasingg. A big thank you to Deadend Fx for the trace of this rare bird that was old in Japan in limited quantites before the millenium. Schematic is avaiable HERE.
