The Electro‑Harmonix J Mascis Ram's Head Big Muff Pi is a signature fuzz/distortion/sustainer pedal developed in collaboration with Dinosaur Jr. guitarist J Mascis. Based on the classic 1973 V2 Violet Ram's Head Big Muff circuit, it comes in a compact die-cast enclosure with a distinctive white and violet finish. Three analogue controls—Volume, Tone, and Sustain—allow adjustment of output level, brightness, and fuzz gain, while true bypass switching preserves signal integrity. Power can be supplied via a 9 V battery or external adapter.
The pedal features a mono input and output and is designed to deliver thick, saturated fuzz tones with pronounced sustain, maintaining note clarity and string separation for both chords and leads. Its circuitry faithfully reproduces the dynamics of the original Ram's Head Big Muff Pi, known for balancing heavy fuzz with responsive touch sensitivity. Its small footprint makes it easy to fit onto most pedalboards without sacrificing versatility.
What sets this edition apart is its signature association with J Mascis, along with the custom graphics that honor his long-standing use of Big Muff pedals. While the core electronics follow the traditional Ram's Head design, the branding and limited-edition presentation tie the unit to Mascis's personal tone, offering fans and players a pedal that combines classic fuzz character with a collector's appeal.
