The Echodriver has been the core distortion sound of Troy Van Leeuwen (Queens of the Stone Age), delivering a harmonically rich, mid-scooped voice with the clarity and power to cut through any mix over his last few years of touring. The tone stack uses a notch-style filter, similar to classic fuzz circuits, offering a broad sweep of EQ flexibility. The Tone control scoops mids at center, rolls off low end when turned down, and rounds off highs when pushed up—letting you shape the pedal’s response to your guitar and amp with surgical precision. Clipping is handled by a dynamic combination of MOSFET and NOS Germanium diodes, producing warm, touch-sensitive gain. A right-side toggle engages Silicon clipping for a more aggressive, compressed response. The left toggle bypasses the tone stack completely, delivering a full-range, unfiltered drive straight to your amp. Powered at 9 to 18 volts (center-negative) for added headroom and punch.
