Finished this one up this weekend. I had a lot of trouble with this one most of which was volume related. At first I couldn't get it to unity much less any boost so I switched to a a100k which got me the volume I wanted but all of the usable range was in the last quarter of the pot. I ended up using a c100k but I think a b100k would have worked equally as well. I also tried it with 2n3904 transistors first but they didn't get as snarly I was hoping so I used 2n2369 transistors with 50-60 hfe to get that quirky Fuzzrite bite.
