With its signature crunch and mids-forward bark, the Big Muff 2 is a take on the long-lost Op-Amp BMP circuit from the 1970s. We’ve added two of our favorite features to expand its tonal capabilities in the Big Muff Pi 2 with Tone Wicker. Expanded top-end and a full-range fuzz make for even more unique muff tones.

Built around the original Big Muff Pi 2 circuit, the pedal has the singing sustain and massive amounts of gain while occupying its very own voice, which sets it apart from the classic Big Muff Pi. A familiar control set of VOL/TONE/SUSTAIN lets you tweak your sound like the original while the TONE and WICKER switches bring even more tones to the table. The TONE switch bypasses the tone knob from the circuit completely creating a full spectrum distortion. The 3-position WICKER switch opens high-frequency filters in the circuit adding two additional levels of bright and clear top-end. This is especially useful with lower TONE knob settings.

The Big Muff Pi 2 with Tone Wicker features a footswitch with Latching/Momentary Action. Click the footswitch for normal latching functionality or press and hold the footswitch of a momentary burst of fuzz mayhem!

  SPECIFICATIONS Circuit Analog Audio Mono Power Supply 9V battery included (optional 9.6VDC-200mA power adapter not included) Dimensions (in) 4.75 x 4 x 2.25 Current Draw 20mA Year Released 2026 UPC 683274012735 Owner's Manual Download         9VDC Power Jack An optional 9VDC, center-negative power supply may be connected to the power jack to provide power without a battery. The Big Muff Pi 2 with Tone Wicker requires 20mA at 9VDC on a center-negative plug. Do not exceed 12VDC at the power jack.   VOLUME Knob Sets the output level of your Big Muff 2 with Tone Wicker.   TONE Knob Provides a range of sounds from high treble to deep bass. As you turn the knob clockwise the treble increases and bass decreases.   SUSTAIN Knob Adjusts the amount of sustain and distortion.   TONE Switch The TONE switch allows the user to activate the Tone knob or to completely bypass the tone circuitry. When the TONE switch is set to the ON position, the Tone knob is active, just like a standard Big Muff Pi 2. When the TONE switch is set to OFF, the Tone knob, and all its circuitry, is bypassed.   WICKER Switch Activate Wicker mode by flipping the WICKER switch up to the HALF or FULL positions. The HALF position adds a touch of high frequency. The FULL position opens-up the high frequency bandwidth for a bright and clear top end. Set the WICKER switch to OFF for the standard Big Muff Pi 2 sound.   INPUT Jack Audio input jack. Impedance: 2MΩ.   OUTPUT Jack Audio output jack. Impedance max: 2.7kΩ.   FOOTSWITCH & STATUS LED Use the soft footswitch to toggle between effect and bypass. The BMP2TW is active when the LED is lit. When the LED is off, the pedal is in buffered bypass mode. The footswitch includes a momentary action: pressing and holding the footswitch for more than half a second returns BMP2TW to the previous state upon release. The momentary footswitch action may be disabled, see the section called Footswitch Latching and Momentary Action.         “One of our creamiest Big Muffs ever!” –Mike Matthews 00:00 / 00:00         Electro-Harmonix Big Muff Pi 2 with Tone Wick...
