The Big Muff Pi 2 with Tone Wicker is an analog fuzz pedal from Electro-Harmonix, released in 20261. It is a take on the long-lost op-amp Big Muff Pi circuit from the 1970s, which Electro-Harmonix describes as having a "signature crunch and mids-forward bark" with singing sustain and large amounts of gain1. What sets this version apart from the standard Big Muff Pi 2 is a pair of switches: a TONE bypass that removes the tone circuitry from the signal path, and a three-position WICKER switch that opens up the high end in two steps1.
Controls and the Tone Wicker switch
The pedal carries the familiar Big Muff control set of VOL, TONE and SUSTAIN knobs, plus two switches that expand what those knobs can do2.
| Control | What it does |
|---|---|
| VOLUME | Sets the output level1 |
| TONE | Ranges from high treble to deep bass; turning clockwise increases treble and decreases bass1 |
| SUSTAIN | Adjusts the amount of sustain and distortion1 |
| TONE switch | ON activates the Tone knob, OFF bypasses the tone circuitry entirely1 |
| WICKER switch | OFF is the standard Big Muff Pi 2 sound, HALF adds a touch of high frequency, FULL opens the high frequency bandwidth for a bright and clear top end1 |
The two switches are where the "Tone Wicker" name comes from. The TONE switch takes the tone control stack out of the circuit completely, which Bass Magazine describes as creating "a full spectrum distortion"2. Gearnews describes the same switch as removing the tone stack "for a raw, high-output sound with zero frequency colouring"3.
The WICKER switch works independently of the TONE knob, adding two levels of extended high-end clarity at any knob setting2. Delicious Audio's Paolo De Gregorio describes it as removing specific high-frequency filters from the circuit, "adding two stages of aggressive, razor-blade top-end bite"4, and says the pedal "can go from a stock, wooly 1970s op-amp grind to a modern, full-frequency assault" via the switch4.
The footswitch is a soft switch with both latching and momentary action. A normal click toggles between effect and bypass, while pressing and holding for more than half a second gives a momentary burst of fuzz that returns to the previous state on release12. The momentary action can be disabled if you prefer plain latching behavior1.
Power comes from the included 9V battery, or from an optional 9VDC center-negative adapter, which is not included. The pedal draws 20mA at 9VDC1.
How it differs from the Big Muff Pi 2
The pedal is built around the original Big Muff Pi 2 circuit, a unique Big Muff Pi design employing two dual op-amps rather than the transistor stages of a classic Big Muff2. Bass Magazine notes it 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"2. Gearnews puts it plainly: with the dual op-amp design "you get the rougher sound the dual op-amp design offers, instead of the smooth sustain of a standard Big Muff"3.
In practical terms, Gearnews describes the Tone Wicker version as "essentially the regular Big Muff 2 (the red one) with a few added tonal tweaks, which may be useful for some"3. The familiar Volume, Tone and Sustain controls are the same as on a standard Big Muff3; the TONE bypass and WICKER switches are what is new32.
Delicious Audio frames the lineage differently, saying EHX "took the concept of a classic Russian or NYC Muff and injected it with steroids"4. Electro-Harmonix's own account ties it to the 1970s op-amp Big Muff Pi circuit12.
Gearnews also notes that the many variations on the Big Muff 2 design can make choosing between them confusing for anyone new to the circuit3. Alongside this pedal, the dual op-amp family includes the Big Muff Pi 2 and the feature-packed Deluxe Big Muff Pi 2, which adds a Wicker switch plus a mids EQ, noise gate and Blend control.
Price
Electro-Harmonix lists the Big Muff Pi 2 with Tone Wicker at $136.10 USD1. At the pedal's announcement in April 2026, Gearnews reported it available to order at Thomann, priced at $1363. Later Gearnews coverage listed a Thomann price of $131.0053, so street pricing at that retailer has varied since launch.
What reviewers said
Coverage at launch was largely descriptive. Bass Magazine highlighted the familiar control set and the two switches that "bring even more tones to the table"2. Delicious Audio's Paolo De Gregorio focused on the range the Wicker switch opens up, from the wooly 1970s grind to a full-frequency modern sound4. Gearnews found the added tweaks potentially useful but cautioned that the number of Big Muff 2 variations makes choosing confusing for newcomers to the circuit3.

Questions
What does the Tone Wicker switch do?
The WICKER switch is a three-position control. OFF gives the standard Big Muff Pi 2 sound, HALF adds a touch of high frequency, and FULL opens up the high frequency bandwidth for a bright and clear top end. It works at any TONE knob setting, and the separate TONE switch can bypass the tone circuitry entirely for an unfiltered, full-range fuzz.
How is it different from the Big Muff Pi 2?
It is built around the same dual op-amp Big Muff Pi 2 circuit, with the same VOL, TONE and SUSTAIN knobs. The difference is the two switches: a TONE bypass switch that removes the tone control from the circuit, and a WICKER switch that adds two levels of extended high-end clarity. Otherwise it keeps the same rougher, mids-forward character.
