ZVex Fuzz Factory

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:
