From the post
The Sunface is a clone of the Dallas Arbiter Fuzz Face, with a few tweaks. First, it has a 50k trimmer at the input of the circuit so you can adjust the pregain (it works exactly like the volume pot on your guitar), second it has an external control for biasing Q2 (the Sundial). Original units use a B5k pot here, which in series with the 2.2k resistor doesn't even equal the original Fuzz Face bias resistor of 8.2k. So you might want to up that pot to a B10k.
Analogman has made both a positive ground, germanium version, and a negative ground silicon version. The germanium versions have NKT275 transistors, and the silicon version uses the BC108. The layout reflects both versions with the perf side showing positive ground, and the PCB side showing negative ground.
