Born from a rare 1970s Milwaukee design, the EHX Percolator brings cult-classic fuzz into the modern era with intuitive controls and boundless sonic range. Asymmetrical clipping and even-order harmonics deliver everything from smooth overdrive to face-melting fuzz, responding dynamically to your touch. Three knobs and a toggle switch unlock countless tones: HARMONICS shapes input gain, BIAS sculpts the character from drive to gated fuzz, and BALANCE controls output level. DRIVE mode offers raw, organic transistor-style saturation; FUZZ mode unleashes heavy clipping. An internal trim pot adds sub-octave depth and extra gain for maximum rumble. True Bypass and dual-action footswitch give you latching engagement or momentary bursts—tap for normal on/off, hold for instant fuzz swells that snap back when released.
