Used Electro-Harmonix J Mascis Ram’s Head Big Muff Pi in good condition, delivering classic Ram’s Head-era Muff sustain with thick, violin-like fuzz and smooth midrange punch. This compact pedal features true bypass switching, standard 1/4" input/output jacks, and runs on a 9V battery or 9V DC center-negative power supply. Ideal for soaring leads, heavy riffs, and creamy, articulate fuzz tones that cut through the mix.
