BP-3 Limited Edition #001

The Limited Edition BP-3 is based on the legendary Harmonic Percolator. This is a very unique fuzz that uses one PNP and one NPN transistor, resulting in an epic even harmonic fuzz.

This fuzz with an attitude is a simple two knob design. Left knob is HARMONICS - this adjusts the amount of input gain driving the transistors, increasing the amount of fuzz as you turn it up. Right knob is BALANCE - this adjusts the volume output.

The BP-3 has three modes of operation - Silicon or germanium clipping, and diode lift.

Toggle up engages a pair of silicon soviet KD522B diodes. The same clipping diodes used in vintage Civil War and Green Russian Big Muff's.

Toggle down engages a pair of germanium 1N965A diodes. Thick, warm clipping.

Toggle middle removes all diodes from the circuit. This increases volume and dynamics. Lift mode can also be a really good sounding boost. Turn the Harmonics (gain) knob all the way counter clockwise and then clockwise just until you hear signal. Then adjust the Balance (volume) to taste.
