In this review post we’re going to be discussing the Electro Harmonix Big Muff Pi, including an overview of its unique features.

Product Description

The classic Electro Harmonix Big Muff Pi is the go-to option for that lovely violin-like sustain sound, eerily similar to the famed Hendrix distortion, and a truly timeless piece of gear. It has a simple user interface with Volume, Sustain, and Tone control knobs.

The iconic and distinctive Electro Harmonix Big Muff PI was invented by Mike Matthews in 1970. The most popular Electro Harmonix pedal, it has that classic rock sound that never goes out of style! For the past 30 years, this iconic piece has defined the sound of rock guitar, with numerous performers relying on its rich, creamy, violin-like sustain to define their music and stun audiences on the world’s largest stages.

The reissue Electro-Harmonix USA Big Muff Pi Distortion/Sustainer Pedal has three controls, just like the renowned Big Muff Pi of the 1970s, allowing you to dial in the finest harmonic distortion/sustain ever manufactured. The output level is adjusted using the Volume control. The Sustain control balances the amount of harmonic distortion in the lengthy sustain. The Tone control lets you choose from a variety of sounds, ranging from warm bass to sharp treble.

Furthermore, its extremely tough chassis assures that it is ready for the road.

Our Verdict

Electro-Big Harmonix’s Muff range is growing for a reason.

First and foremost, these pedals have long been popular and well-respected among guitarists of many types and genres around the world.

Second, these fuzz pedals provide some of the most recognizable guitar and bass tones ever developed, inspiring new generations of guitarists to employ them.

A parametric midrange EQ section with up to 10dB of boost/cut, as well as a Wicker switch for tuning in your high frequencies as you see fit, were incorporated in addition to the standard Sustain, Tone, and Volume controls.

As if that wasn’t enough, EHX threw in a wet/dry Blend control as well as a noise gate to keep unwanted noise at bay.

The Big Muff Pi, like other Electro-Harmonix pedals, is built to last. You can use this pedal in a variety of settings, including the road, the studio, and bar gigs. It’s extremely long-lasting and dependable.
