From the vendor

The original potentiometers are also attached to the board, but ZVex uses small square potentiometers, which are more expensive. I wanted a layout that used regular 16mm pots that are easier to find and probably already in your parts stash. Q2-3s were originally AC128, but any germanium PNPs should work just fine. The Hfe ranges should be around 70-100 and 100-150 respectively (very similar to Fuzz Face).
