Hand-built Harmonic Percolator recreation by Hardware Fixations

A touch-sensitive vintage gain pedal that rides the line between overdrive, distortion, and fuzz. Inspired by the rare 1970s Interfax Harmonic Percolator, it emphasizes rich even-order harmonics, responsive pick attack, and wide-open dynamics instead of heavy compression. Your guitar stays alive, textured, and expressive under your fingers.

Three distinct clipping modes give you immediate, musical choices:
• Silicon — Sharp, immediate vintage distortion with clarity and bite.
• No Clipping — Raw, open, and organic — pure transistor overdrive character.
• Germanium — Smooth, fuzzy overdrive with vintage warmth and natural sag.

Built one at a time with premium thru-hole components right here in Winston-Salem, North Carolina. Every unit is obsessively tested and comes with a real lifetime support promise: if it ever stops working, send it back and I’ll fix it, replace it, or refund your purchase.
