From the post
Traced by Unsound Circuitry, once again, thanks, mate! It is a well known fact that this is a modified Ge Fuzz Face. The stock Fuzz control is ditched and replaced with a "Pre Gain2 control. It runs on normal power supply and is powered by soviet MP37B NPN germanium transistors. These are usually faily low gain and the current leakage is low. The bias trimpot is placed on the side of the board for easy moddong for an external bias pot.
