J Mascis Ram's Head Big Muff Pi

The J Mascis Ram’s Head Big Muff Pi fuzz pedal pays homage to the sonic center of the alt-rock legend’s iconic tone of equal parts thickness and clarity in a special edition white and violet finish.

“That’s my sound. The Muff is always on,” J says. “All distorted sounds begin with the Muff. That’s what I grew up playing so it’s kind of amazing to have my own signature one.”

Based on the highly coveted 1973 Electro-Harmonix V2 Violet Ram’s Head Big Muff, J’s signature Big Muff produces the indulgent fuzz and exceptional sustain used as his sonic center for decades.
