Electro-Harmonix Nano Bass Big Muff Pi 2 Pedal

Fusing the Big Muff's storied history as a favorite fuzz pedal amongst bassists with the long-lost Op-Amp fuzz that never was is the Bass Big Muff Pi 2. With a surprising tone all its own, the Big Muff Pi 2 made waves when the original circuit from the 1970s was resurrected in collaboration with Josh Scott of JHS Pedals. This take on the iconic pedal is optimized for bass players looking for a tasty fuzz without sacrificing any low-end flavor.

The Bass Big Muff 2 features the signature midrange grind of the original with the flexible EQ and virtually endless sustain expected in any Big Muff. The Bass version adds a BLEND knob and BASS BOOST switch to the VOL, SUSTAIN, TONE control set. The BLEND knob mixes the dry and fuzz signals to set the perfect balance of distortion without losing clarity and foundational low-end. Flip the BASS BOOST switch to make an even bigger impact, especially while running the TONE knob at higher, more trebly settings. These added controls let the bass player dial in the best fuzz tone without sacrificing their ability to shake walls and rattle halls.

The Bass Big Muff Pi 2 features a true bypass footswitch with Latching/Momentary Action. Click the footswitch for normal latching functionality or press and hold the footswitch of a momentary burst of fuzz mayhem!
