Description

Product details

The Electro-Harmonix Big Muff Pi with Tone Wicker is a distortion/sustainer pedal that preserves the classic Big Muff Pi sound while adding two unique controls. A Wicker switch opens three high-frequency filters for brighter, more defined sustain, and a Tone switch bypasses the tone circuit entirely for a raw, high-output drive with uncolored gain. Controls include Sustain, Tone, and Volume knobs. True bypass switching preserves the bypassed signal path. The pedal runs on a 9V battery or a center-negative 9VDC supply rated at 50mA (EHX recommends the US96DC-200BI). A 9V battery is included. The die-cast metal chassis is built for pedalboard use.
