Harmonic Percolator
A faithful recreation of the Interfax Harmonic Percolator
A two transistor texture machine that doubles as a box of chaos. This lesser known fuzz was designed by an eccentric Wisconsin engineer in the early 70’s and has gone on to amass a cult following. The circuit is based around a hybrid silicon / germanium common emitter amplifier that clips asymmetrically and imparts the signal with a highly textured fuzz. If you're a fan of the guitar tones on "In Utero" this will be a great addition to your arsenal. This version features a three position diode switch for altering the clipping character (Ge / Si / diode bypass).
