Here’s my take on the ZVex Fuzz Factory. The originals have the pots mounted to the board as well, but ZVex uses the little square pots which are more expensive. I wanted a layout that used regular 16mm pots, which are easier to come by and what you probably already have in your parts stash. Q2-3 originally were AC128s, but any PNP germaniums should work fine. I believe ZVex has used a variety of different germaniums over the years. Hfe ranges should be around 70-100 and 100-150 respectively (much like a Fuzz Face).
For what it’s worth, most of my layouts with onboard pots are meant to be mounted from the solder side of the board, like this:
You can do the same for this layout, but it’s designed for the pots to be on the same side as the rest of the components, like this:
This way, the board will be vertical inside the enclosure, and the controls will be aligned like the original:
