Electro-Harmonix Nano Metal Muff

Electro-Harmonix · pedal

The Electro-Harmonix Nano Metal Muff is a compact high-gain distortion pedal delivering aggressive metal tones with the characteristic Muff-derived harmonic density and bottom end. It features Distortion, Tone, and Volume controls in the nano footprint, providing a range from moderately heavy crunch to extreme saturation suited for metal riffs and lead playing. A mid-scoop voicing gives it a scooped, modern metal character. Well suited to heavy metal, hard rock, and high-gain applications where a compact, single-purpose high-gain distortion with established tonal character is needed.
