  • ℹ️ Description

Demo of the Fredric Effects Harmonic Percolator.

This is an improved clone of the Interfax Harmonic Percolator, an oddball overdrive/distortion pedal from the 1970s popularised by Steve Albini of Shellac. A switch to alter the clipping diodes, for a more open overdriven sound, adds to the versatility of the effect.

Powered by battery or standard center-neg DC jack, clear red LED. Small, MXR-sized enclosure. Pedals are hand-made and individually tested.

I used one of these in Assault & Battery's Battery 2 studio, and it was my favourite dirt pedal I used. It's pretty apt that the diode sign looks just like our logo - it reinforces the fact that I need one!

From this demo alone, this one sounds closer than the Karma Suture.. But god damn if I don't want the interfax one.

Not once did you touch that toggle switch though.
