Electro-Harmonix Classics USA Big Muff Pi Distortion/Sustainer Guitar Effects Pedal

The Electro-Harmonix Classics USA Big Muff Pi distortion/sustainer guitar effects pedal is the stompbox that set the standard for fuzz tone. For over 40 years, the Big Muff Pi has been revered by guitar legends and contemporaries alike for its rich, creamy distortion and violin-like sustain.

Dial in Your Perfect Distortion

Like the original '70s Big Muff Pi, the reissue features three controls—Volume, Tone and Sustain—that provide a spectrum of distortion styles. Crank the Volume for a boost to cut through the mix, increase the Sustain for endless sustain and harmonics, and sweep the Tone from a warm, bassy purr to a sharp, trebly bite. With just a few tweaks of the controls, you can achieve the signature Big Muff Pi sound or forge your own.

A Piece of Music History

The Big Muff Pi earned its status as a legend for its use on countless classic rock recordings. Guitar gods, such as David Gilmour, Carlos Santana and Jimi Hendrix, relied on the Big Muff Pi to create their iconic tones. Today, contemporary artists from Jack White to Muse keep the tradition alive with the Big Muff Pi on their pedalboards. With a pedigree like that, the Big Muff Pi shaped rock music as we know it.

Roadworthy and Gig-Ready

Despite its historic roots, the Big Muff Pi is not just a relic of rock's golden age. It's a workhorse pedal built for today's players. The compact, rugged enclosure can withstand the rigors of the road while the simple, intuitive controls make it easy to dial in your tone on the fly. Power it with a 9V battery or any standard 9V DC power adapter (sold separately).
