This is an improved clone of the Interfax Harmonic Percolator, an oddball overdrive/distortion pedal from the 1970s popularised by Steve Albini of Shellac. Built to the most recent ‚general consensus‘ schematic, only with the addition of a switch to offer three different clipping options which adds to the versatility of the effect.
All the hard-to-find parts of the originals, but in a modern pedal-board friendly package, with DC power, LED indicator and normal rotary pots instead of sliders.
Custom enclosure fabricated for Fredric Effects in North London
Professional powder coating and screen print
PCB construction (not perf or vero)
Alpha footswitch and pots
