The Electro-Harmonix XO Bass Big Muff PI Distortion Effects Pedal, a pioneering pedal that gives bass players the iconic fuzz of the Big Muff Pi optimized for full-bodied bottom end. Drawing on two classic Muffs that bassists have long used, the Bass Big Muff Pi creates tones reminiscent of the battle-tank green Sovtek Big Muff Pi and the legendary '70s Electro-Harmonix Big Muff Pi—but with beefed-up lows that cut through the mix. A direct out allows for feeding an unadulterated signal to a second amp or effects chain, while a Bass Boost/Dry toggle augments the Bass Big Muff Pi's formidable sound with additional low-frequency warmth. The Prodigy is reborn with underworld instincts, wielding the drive of the original classic Big Muff Pi and the earthy support of a bass-tailored design with no loss of low end. This is the pedal bassists who love the Big Muff sound have been waiting for.
