Electro-Harmonix J Mascis Ram's Head Big Muff

Electro-Harmonix · pedal

The Electro-Harmonix J Mascis Fuzz is a signature fuzz pedal endorsed by J Mascis of Dinosaur Jr, delivering the heavy, sustaining fuzz tones associated with Mascis neo-psychedelic rock and shoegaze lead playing. J Mascis is known for his use of Big Muff-style fuzz into loud amplifiers, producing the heavily saturated, singing lead tones that define Dinosaur Jr recordings from the late 1980s through the present. The signature pedal provides a fuzz character suited to heavy psych rock, alternative, and shoegaze applications where maximum fuzz density and sustain are the primary requirements.
