Here is a verified layout of a rare bird, Carlsboro 2 Knob Fuzz. Not much info on this one and it's not a tonebender variant.



I don't have any OC71 transistors so auditioned several others. AC128 were very hissy with an unpleasant decay, SFT306 were a bit better but still some gating. Tried some russian trannies  like MP16B and MP21D - Viola!. Great stable fuzz sound with long sustain. The Attack pot is more like a tone or presence control. Counter clockwise it is quite comressed and bordering to Big Muff territory and clockwise it opens up, gets louder and brings in higher mids.



I did an NPN version as well, and with MP38's it rips.

Cheers
