A request from Mikko, who had very kindly done all of the tracing work - very nice job by the way, and photos below.
It's a Fuzz Face from Sonus using NKT MT57 germanium transistors, with an external bias pot and a couple of different component values (Jimi mods) - 2k fuzz pot and a 1k resistor instead of 470ohm.
As you can see I did two versions on tag board, one a bit smaller and one with a bit more room. Both have enough space for a mounting screw.
In addition to the battery, the Sonus pedal does have a DC input - I can see electrolytic poking out from shrink wrap, I'm guessing there may also be a diode hidden in there for polarity protection as well, but who knows. Not hard to add this off board or just go without if you plan on battery only - this a positive ground effect, so for some people DC is not an option.
