Fredric Effects Harmonic Percolator



Fredric Effects

This is a clone of the Interfax Harmonic Percolator overdrive/distortion, an oddball asymetrical clipping pedal popularised by Steve Albini of Shellac. Built to the most recent 'general consensus' schematic, with the addition of a switch to disengage the clipping diodes, for a more open overdriven sound, which adds to the versatility of the effect.

All parts are the best quality available. True bypass via Alpha footswitch, powered by battery or standard center-neg DC jack, clear orange/red LED. Neutrik jacks. Pots are Alpha. PCBs are fibreglass. Pedals are hand-made, individually tested and guaranteed for the first owner for two years.

The noise reduction circuit in the black percolator is fully bypassable via a series of DIP switches on the circuit board. The key to these is printed inside the pedal.

Small, MXR-sized enclosure (with a new design that owes a fair bit to their great-looking script-logo pedals!)

Professionally painted and screen printed percolators for a tough, long-lasting finish.

Specs are as follows:

  • Beige: NOS Russian MP16B Ge & standard 2N3904 Si transistors, Russian KD514A silicon diodes (£70)
  • Blue: Vintage correct NOS 2N404(A) & 2N3565 transistors, 1N695 Germanium diodes (£85)
  • Black: As blue, with Wima audio-grade capacitors, precision metal film resistors, switchable noise reduction circuit (£100)
