Harmonic Percolator
So this is a clone of the old Interfax Harmonic Percolator. I used a board from Fuzz Dog's Pedal Parts in the UK. I built this pedal using a vintage BC108 with an hFE of 284 for the silicon transistor and a vintage Tesla 104NU71 with an hFE of 60 for the germanium transistor.
It's...odd. Sometimes strange and splatty. Sometimes furry and warm. Switching out the diode clipping makes it even more obviously quirky. It's a very unusual fuzz pedal.
