Introduction
The Electro-Harmonix Nano Metal Muff is a compact, high-gain distortion pedal designed for electric guitar, featuring an integrated noise gate. This pedal provides extensive tonal shaping capabilities suitable for various metal genres, from percussive rhythms to soaring leads. Its robust construction and intuitive controls make it an essential tool for achieving aggressive, articulate distortion.

Setup
Follow these steps to properly set up your Nano Metal Muff pedal:
- Power Connection: The Nano Metal Muff can be powered by a 9V battery (included) or an optional 9V DC power adapter (center-negative). To install the battery, remove the four screws on the bottom plate of the pedal. Connect the 9V battery to the battery clip inside the pedal. For external power, connect the adapter to the 9V power jack located at the top of the pedal.
- Input Connection: Connect your electric guitar or other instrument to the INPUT jack on the right side of the pedal using a standard 1/4-inch instrument cable.
- Output Connection: Connect the OUTPUT jack on the left side of the pedal to your amplifier's input or the next pedal in your signal chain using another standard 1/4-inch instrument cable.
- Activation: Press the footswitch to engage or bypass the effect. The STATUS LED will illuminate red when the effect is active.

Operating Controls
The Nano Metal Muff features six control knobs and two indicator LEDs:
- VOL (Volume): This knob controls the overall output volume level of the pedal. Adjust clockwise for higher volume.
- GATE: This knob adjusts the threshold of the built-in noise gate. Turning it clockwise increases the gate's sensitivity, effectively muting unwanted noise and hum when no signal is present or when the signal falls below the set threshold. The GATE LED illuminates green when the noise gate is active and muting the output signal.
- DIST (Distortion): This knob controls the amount of input gain and distortion. Turning it clockwise increases the intensity of the distortion effect, from subtle crunch to heavy, saturated metal tones.
- TREBLE: This knob provides +/-10dB of boost or cut for the high frequencies. Adjust to shape the brightness and presence of your tone.
- MID: This knob offers +/-15dB of boost or cut for the mid-range frequencies. The mid-range control is crucial for shaping the character and punch of your metal tone.
- BASS: This knob provides +/-14dB of boost or cut for the low frequencies. Use this to add depth and thickness to your sound.
- STATUS LED (Red): Indicates whether the pedal effect is engaged (on) or bypassed (off).
- GATE LED (Green): Indicates when the noise gate is actively muting the output signal.

Maintenance
To ensure the longevity and optimal performance of your Nano Metal Muff pedal, consider the following maintenance tips:
- Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Avoid using abrasive cleaners or solvents, as they may damage the finish or internal components.
- Storage: When not in use for extended periods, disconnect the power supply or remove the 9V battery to prevent battery drain and potential leakage. Store the pedal in a cool, dry place away from direct sunlight and extreme temperatures.
- Connections: Periodically check all cable connections for wear and tear. Ensure jacks are free of dust and debris.
- Battery Replacement: If using battery power, replace the 9V battery when the pedal's performance degrades or the STATUS LED dims.
