Overview
The J Mascis Ram’s Head Big Muff Pi Artist Edition Fuzz is a precision-engineered homage to the sonic foundation of alt-rock legend J Mascis. Designed to capture the specific balance of thickness and clarity that defines his iconic tone, this pedal is based on the highly coveted 1973 Electro-Harmonix V2 Violet Ram’s Head Big Muff. Whether used as a primary distortion source or a constant layer of grit, this signature pedal delivers the indulgent fuzz and exceptional sustain required for massive, wall-of-sound guitar textures.
