The EHX Nano Metal Muff was built for the player who demands nothing less than hard-hitting distortion and an intense, aggressive sound. It’s a combination of weaponized distortion and an extremely powerful EQ section that provides all the flexibility and tone-shaping needed to dial in an array of ultra-heavy sounds. The Nano Metal Muff’s newly designed noise gate is a superb addition to this high-gain pedal and eliminates unwanted hum when you stop playing. It features a noise floor threshold control (GATE) and its own LED to indicate when the gate is engaged.
