Frequently Asked Questions - Metal Muff Electro Harmonix
How do I power the Metal Muff?
You can power the Metal Muff using a 9V alkaline battery or an optional 9V DC adapter with center negative polarity (2.1mm barrel). The adapter should provide at least 100mA.
How do I connect the Metal Muff to my guitar and amplifier?
Connect your guitar to the input jack (left side) and connect the output jack (right side) to your amplifier input. Use standard 1/4 inch instrument cables. The pedal works best when placed at the beginning of your signal chain.
What do the controls do?
The Volume knob controls output level. Tone adjusts the overall EQ. Distortion sets the amount of gain. The Top Boost switch adds a high-mid frequency boost for increased presence.
Why is the LED not turning on?
Ensure the pedal is powered (battery inserted or adapter connected). If using a battery, check that it is fresh. Press the footswitch to engage the effect; the LED should light up when the effect is active.
Can I use the Metal Muff with bass guitar?
Yes, the Metal Muff works with bass guitar and is popular for creating heavy, distorted bass tones. Adjust the Tone control to suit the bass frequencies.
How do I change the battery?
Remove the four screws on the bottom plate of the pedal. Lift the plate to reveal the battery compartment. Connect the battery snap to a new 9V battery, then replace the bottom plate and screws.
What is the Top Boost switch for?
The Top Boost switch adds a mid-high frequency boost that helps your guitar cut through a dense mix, especially useful for solos or heavy riffing.
Is the Metal Muff true bypass?
Yes, the Metal Muff features true bypass switching, ensuring your guitar signal remains unaffected when the pedal is turned off.
How do I clean the Metal Muff?
Unplug the pedal and remove power. Wipe the exterior with a soft, dry cloth. Do not use any liquids or abrasive cleaners. Avoid getting moisture inside the pedal.
What should I do if the pedal stops working?
Check the battery or power adapter. Try a different instrument cable. If the problem persists, contact Electro-Harmonix customer support or an authorized service center. Do not attempt to open or repair the pedal yourself.
