The Fredric Effects Harmonic Percolator is an accurate clone of the Interfax Harmonic Percolator, an oddball overdrive/distortion pedal from the 1970s popularised by Steve Albini of Shellac. It is built to the most recent ‘general consensus’ schematic, arrived-at by careful disassembly and measuring of original Harmonic Percolator pedals. The only change Fredric Effects have made is the addition of a switch to offer three different clipping options which adds to the versatility of the effect.
If features all the hard-to-find parts of the originals – new old stock Germanium transistors and diodes from the 1970s – but in a modern pedal-board friendly package, with DC power, LED indicator and normal rotary pots instead of sliders.
High quality construction:
– Custom enclosure fabricated for Fredric Effects in North London
