The Utility Perkolator is our latest version of the fabled Interfax Harmonic Percolator from the 1970s. The Harmonic Percolator is a simple yet fascinating circuit which readily lends itself to tweaking and improvement. We already build a faithfully vintage correct version of the Harmonic Percolator, however the Utility Perkolator takes this circuit in another direction. Using higher gain, lower leakage Russian Germanium transistors, and a low pass filter which only removes the high-end hisses and glitches associated with the HP, the Utility Perkolator has a considerably lower noise floor. The result is a tighter and more controllable effect which is still capable of producing the classic Harmonic Percolator sound.
We believe this is the best sounding Harmonic Percolator you can buy. The MkII Utility Perkolator features a two colour screen print in silver metallic and black.
