Built it. Works. Sounds Great! I used a 2N2369 with 64 hfe, and of course the 2N5089. Much like every other circuit with a 1k gain pot, this could really use a C1k.
This is a really good sounding pedal. It really does a lot and goes from a pretty clean boost to a full on melt down. Just wanted to share that it's totally worth building if anyone is on the fence. Definitely C1k for fuzz.
