I saw this on dirtbox layout, I think, and although I'm not much of a boost guy, the circuit seemed to be interesting with its J201/Germanium topology.
After populating the vero, I remembered that I had some "why not both" transistor PCB laying around, so I made the GE switchable (GT309B / SFT317).
I tried a few GE transistors, some sounded similar, some had a clearly different flavor, and it was interesting to hear that hFe didn't really matter, at least in terms of volume on tap. This pedal can go loud!
Also very cool is the Gain (or bias?) knob outside, it goes from clean boost, to that famous edge of breakup (on bass) to dirty boost to fuzzy. Great pedal that sounds bloody fantastic on bass and guitar. Actually my guitar player said after 2 minutes with it "I absolutely need this!". He's currently using an Echoplex preamp/boost.
