The Electro-Harmonix Percolator is a fuzz pedal that channels the spirit of a legendary 1970s design from an audio repair shop in Milwaukee. This pedal is a modern reinterpretation of the rare Interfax HP-1 Harmonic Percolator circuit, renowned for its unique tonal qualities. Whether you're looking for a subtle overdrive or a massive fuzz, the Percolator's asymmetrical clipping delivers enhanced even-order harmonics, providing a rich and dynamic sound palette that responds beautifully to your playing dynamics.

At the heart of the Percolator is its intuitive control layout, featuring Harmonics, Balance, and Bias knobs. The Harmonics knob lets you fine-tune the input gain, transitioning from a gentle overdrive to a saturated fuzz. Meanwhile, the Bias control shapes the gain circuit, allowing you to explore everything from smooth sustain to edgy, gated fuzz sounds. The Balance knob adjusts the overall output level, ensuring your sound cuts through the mix.

A versatile Drive/Fuzz switch gives you the choice between a raw transistor-style overdrive and a heavier, saturated fuzz tone. The pedal's internal trimpot offers an additional layer of customization, enabling you to add more gain and focus on sub-octave tones for an extra dimension of sonic depth. True bypass switching and both latching and momentary footswitch options ensure that your clean tone remains unaltered when the pedal is disengaged.
