Electro Harmonix Little Big Muff Pi
Electro-Harmonix XO Little Big Muff PI Distortion Guitar Effects Pedal Little Big Muff puts this legendary distortion/sustainer in a more compact and rugged die-cast box, but the sound is true to the 1970 original-silky smooth violin-like sustain that lets you hold a note for an entire set. Sustain, Tone, and Volume knobs.
