Fredric Effects Utility Perkolator – the best Harmonic Percolator

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.
