Electro-Harmonix Nano Metal Muff Distortion with Noise Gate. Built for the player who demands nothing less than hard-hitting distortion and an intense, aggressive sound! 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. A compact footprint and intelligent, straightforward controls complete the picture. Product Highlights: Voiced for the heavy metal player. Compact, pedalboard friendly footprint. Extensive EQ control: Bass +/- 14dB of cut or boost, Mid +/- 15dB and Treble +/- 10dB. VOL (volume) sets the pedal’s output volume level. DIST adjusts input gain and distortion. Noise gate eliminates unwanted noise and includes an LED to indicate when the output signal is muted. 9V battery included. Product Features: Volume Knob: Sets the overall output level. Gate Knob: Removes unwanted hum by adjusting the noise floor threshold. The gate mutes the OUTPUT jack when the signal at the INPUT jack is below the threshold setting of the GATE knob. As GATE is turned clockwise, a louder guitar signal at the input jack is required to unmute the OUTPUT jack. Set GATE fully counter-clockwise to disable. Distortion Knob: Adjusts the amount of distortion and saturation. Turn clockwise for more saturation. Treble Knob: Provides up to 10dB of cut and boost in the treble frequency range. Mid Knob: Provides up to 15dB of cut and boost in the middle frequency range. Bass Knob: Provides up to 14dB of cut and boost in the bass frequency range. Output Jack: The 1/4" jack is the audio output from the Nano Metal Muff. In Bypass mode, the OUTPUT jack is connected to the INPUT jack through a buffer circuit. The output impedance at the OUTPUT jack is 600Ω. Input Jack: This 1/4" jack is the audio input to the Nano Metal Muff. The input impedance presented at the INPUT jack is 1MΩ. Bypass Footswitch and Status LED: Toggles the Nano Metal Muff between effect and buffered bypassed. The STATUS LED lights when the pedal is engaged. Product Specifications: Circuit: Analog. Bypass: Buffered Bypass. Audio: Mono. Power Supply: 9V battery included (optional 9.6VDC-200mA power adapter not included). Dimensions (in): 4.5 x 2.75 x 2.1. Current Draw: 24mA. Year Released: 2021.
