With a sound patterned after the tank-green Russian Muff, the Electro-Harmonix Nano Bass Big Muff Pi packs ginormous fuzz tones into a nano-sized enclosure. This bass effects pedal includes the familiar Muff 3-knob layout for tailoring your grit, along with a Dry switch that blends your dry signal with the Nano Bass Big Muff Pi’s distortion. You also get true-bypass switching to preserve your tone when the pedal isn’t in use. A roadworthy die-cast chassis ensures that this stompbox can withstand plenty of enthusiastic stomps. The Nano Bass Big Muff Pi gives you everything from a touch of growl to blistering cacophony, and it does it without taking over your pedalboard.
