Fuzz

J Mascis signature Ram's Head Muff delivering the Dinosaur Jr. guitarist's classic fuzz tone.

Electro-Harmonix worked with J Mascis of Dinosaur Jr. to create his signature Ram's Head Big Muff. His massive fuzz sound defined indie rock.

Based on the Ram's Head era (1973-1977) that Mascis prefers. Added scoop switch for extra mid control. The circuit captures that wall-of-fuzz sound from You're Living All Over Me and Bug.

Nano enclosure with Dinosaur Jr. purple graphics. True bypass. Mascis tested and approved.

The Dinosaur Jr. fuzz sound, officially.
