The Particle Germanium Fuzz is an adaptation of the Interfax HP-1 Harmonic Percolator, an extremely rare and highly sought-after fuzz/overdrive from the mid-1970s. The Harmonic Percolator is a two-transistor fuzz, but has no similarity to other pedals like the Fuzz Face or a Tone Bender variant. It uses a PNP germanium transistor paired with an NPN silicon.
This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 2 knobs for 6,3mm shaft separately.
