Heartbeat Percolator
Harmonic Percolator with silicon transistors and three clipping modes, from low-gain drive to fuzz.
Limited-edition Harmonic Percolator sharing the same circuit as the HP-X with unique artwork. A versatile distortion inspired by the Interfax Harmonic Percolator, using carefully selected silicon transistors for reliable biasing and temperature-stable performance.
Features Harmonics and Balance controls plus a three-position clipping switch selecting between asymmetrical germanium diodes, diode lift for all-transistor distortion, and symmetrical silicon diodes. Variable input impedance places it comfortably anywhere in the signal chain.
Sweeps from harmonic-rich low-gain overdrive to completely squished-out gated fuzz. Handmade near Philadelphia, PA.
