From the post

Happy Fuzz Friday everyone! You probably didn't miss this collaboration between Josh Scott and Mike Matthews, and because of the old school style of the big box version, it wasn't to hard to trace. There's still a few things we don't know about the circuit, so have your sockets handy if you put this together (see notes below). There's some debate over the touted originality of the circuit, as it appears to be a Bazz Fuss into a Tim Escobedo PushMe PullYou, but do your best and leave that discussion to the forums. FSB trace thread for reference.

Notes:

• Q1 is a large can (TO-39 by the looks of it) transistor. I doubt it's germanium, so I assume it's something relatively low hFE like a 2N1711. I'd try out 2N2222A, 2N3904, 2N5550 and see what works/sounds best. The transistor types listed in the layout are an assumption based on the PushMe PullYou. • D1 appears to be old stock of some sort, with orange and green color bands. I would assume a 1N4148 will work just fine here like in a typical Bazz Fuss. • C1 is a small ceramic cap, value unknown. I'd start experimenting with anything between 100-470p. • The 10uF cap off lug 2 of the Balance pot is an assumption based on the PushMe PullYou. It could be as large as 100uF as it's the same size axial capacitor in the original as the power filter caps.
