Bulldozer Percolator

Limited-edition Harmonic Percolator sharing the same circuit as the HP-X with different artwork. A versatile distortion inspired by the Interfax Harmonic Percolator, built with silicon transistors for consistent biasing and temperature stability.

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 ensures it sounds great anywhere in the signal chain.

Ranges from harmonic-rich low-gain drive to blown-out gated fuzz. Handmade near Philadelphia, PA.
