I’ve been wanting to do a Fuzz Face with on-board pots for a while, and when I stumbled across a schematic of Jack Deville’s (Mr. Black) take on the classic circuit, things just fell into place. This uses NPN germanium transistors (though you could use silicons if you must), and I tried to leave plenty of room for them if you’re using some of the big Russian germaniums easily available off eBay (GT404, MP38, etc). You could build a standard Fuzz Face on this board, just mind the component changes and replace the resistor from Fuzz 1 to ground with a jumper.
Update 5/4/15:
Verified this last night. Here’s a pic of my build.
Used some Russian мп38 germanium transistors (Q1: 80 hfe Q2: 110 hfe) and a 7.5k resistor in place of the 10k trimmer (ran out of those). For the input cap I tried out a couple different values (47n, 100n, 220n…) but settled on 39n, as it seemed to give more clarity that higher values. Socket and experiment.
