UTILITY PERKOLATOR

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 germanium clipping diodes, for a more open overdriven sound, which I think adds to the versatility of the effect.
