Four silicon transistors provide smooth fuzz and sustain with a tone knob for wide tonal range with the Electro-Harmonix Big Muff Pi stompbox.

Like the legendary Big Muff Pi of the '70s, the reissue Electro-Harmonix USA Big Muff Pi Distortion/Sustainer Pedal has 3 controls that let you dial in the finest harmonic distortion/sustain ever produced. The Volume control adjusts the output level. The Sustain control optimizes the long sustain with just the right amount of harmonic distortion. The Tone control provides a range of sounds, from warm bass to crisp treble. From Pink Floyd to the Chemical Brothers to Korn, the distortion / sustain pedal, made in New York City, USA.

To achieve its long sustain, the Electro-Harmonis Big Muff Pi distortion sustain effects pedal has very high maximum gain. This requires that pickups and cables be well shielded and properly grounded to avoid excessive hum when high sustain control settings are used.
