Electro-Harmonix Deluxe Big Muff Pi 2 Review: A Maxed-Out Take on a Lost Circuit (2026)

Electro-Harmonix has unveiled a new pedal, the Deluxe Big Muff Pi 2, which is a modern take on a classic fuzz circuit. This pedal is a maxed-out version of the original Big Muff 2, designed to offer players more control and flexibility over the fuzz tone. The story behind this pedal is intriguing; it was derived from a lost schematic, found in the archives of the original designer, Bob Myer. This circuit was always a bit of a cult favorite, prized for its mids-driven snarl, which is a stark contrast to the scooped tones of many Big Muffs. The Deluxe Big Muff Pi 2 builds on this foundation, adding extra controls and features that enhance the player's experience.

One of the standout features of this pedal is its parametric mids section. This section now has its own footswitch, allowing players to boost or cut mids across a wide range. Additionally, a Hi/Lo Q switch provides tighter or broader resonance, giving players even more control over the tone. The three-way Wicker switch opens up two levels of extra top-end filtering, which is particularly useful for dragging brightness and definition out of darker, woollier tones. An adjustable gate keeps hiss and hum in check when the sustain is pushed hard, ensuring a clean and controlled sound.

The Deluxe Big Muff Pi 2 also offers a range of other features, including latching and momentary modes on the bypass footswitch, a trim pot for extra gain and distortion, and an all-analog, mono design that draws 45mA and ships with an EHX 9-volt supply. These features, combined with the extra controls and flexibility, make this pedal a standout in the world of fuzz pedals.

In my opinion, the Deluxe Big Muff Pi 2 is a must-have for any guitarist looking to add a unique and versatile fuzz tone to their rig. Its ability to shape the fuzz before it hits the amp, combined with its range of controls and features, makes it a truly remarkable pedal. The fact that it is based on a lost circuit only adds to its intrigue and appeal. Personally, I think this pedal is a testament to Electro-Harmonix's commitment to innovation and their ability to take classic designs and push them to new heights.
