So far I have traced the Pruely Fuzz. It appears to be nearly dead on..The Red Fuzz you can find the schematic at General Guitar Gadgets. The input cap is larger and the feed back loop cap is smaller. Otherwise they use all full size parts and through hole. Actually well built.
I looked over their compelling drive. I am pretty sure it's an OCD power by a 4558 rather than a TL082. I will trace it out soon.
Anyone else have a look at these?
