Another interesting circuit from Spaceman, traced by Dino T.. The vero is verified and I decided to include Dino's mods. The Depth Switch is a internal DIP switch in the original pedal, here it's external. Also the trimpot replaced the 16k resistor found in the original. This allows you to try different types of vactrols or LED/LDR combos.
It's quite picky about transistor selection, Q1 and Q2 needs to be matched, otherwise it will gate and the fuzz will sound ugly. BC179C and BC109C with hfe 573 and 571 worked best for me here. The original had a P416A for Q3 which is a low gain and low leakage russian PNP germanium. Many low gainers sounded good here but a settled with a MP40 (Hfe 52).
