A concoction of my own, I call it the Doom Face!
It’s a COT50 (acting as a sort of pre gain/boost) going into a silicon Fuzz Face (Q1 - MPSA13 Darlington / Q2 - BC108) that then goes into a Stratoblaster to push the amp input stage harder.
Also put a rotary input tone cap switch on the FF to dial in extra low end (goes up to 10u) and also more gain. Big caps all round for max low end. The result is a massive saturated wall of fuzz, perfect for dooming up!
Heavily inspired by Nick @Dunwich Amps who also gave me some tips on how to doom out a Fuzz Face, nice one!
All Fuzz Dog boards, box etched with Caustic as per norm. I also used the font from the game Doom for extra doom. Doom.
