Original Electro-Harmonix Big Muff Pi (Made in USA) – A classic fuzz​/​distortion pedal known for its rich, creamy sustain and iconic tone. This unit is in good working condition, with some cosmetic wear consistent with age: scratches to the paint on the top surface and Velcro affixed to the base, securing the battery holder in place. Fully functional and all-original components. A great piece for collectors or players seeking vintage tone with authentic character. Only tested on battery power, power adapter not included.
