Featuring an ultra-compact enclosure and the same controls for volume, tone and sustain, the Electro-Harmonix Nano Big Muff Pi brings the same creamy fuzz and distortion as the original in a pedalboard-friendly package. Built using the same Big Muff Circuitry in a nano format, this effect is a great introduction to the Big Muff World or just a great fuzz pedal that won't eat up pedalboard space or cash.
