Electro Harmonix Double Muff Nano Fuzz/Overdrive Guitar Pedal w/ 9V Battery Nano

Electro Harmonix Double Muff Nano Fuzz/Overdrive Guitar Pedal w/ 9V Battery Nano Part Number: DOUBLE MUFF

Classic dual overdrive. The original 1969 plug-in Muff Fuzz had just a touch of overdrive and sounded like a vintage amp with a slightly torn speaker. We paired two of these together in one box to create the Double Muff. Use just one Muff for a hint of milky distortion, or cascade the second Muff for over-the-top overdrive that turns the milk into cream. Two distortions in one!

Quick Specs

In single mode, the amount of overdrive will lessen as you decrease the volume on your guitar. You can compensate for this by increasing the volume of the Single Muff. In Double Mode, the Muff knobs will interact with each other so that you can tweak your sound for the perfect amount of distortion every time.


SINGLE/DOUBLE Switch-Selects between one Muff in SINGLE mode or two Muffs in series in DOUBLE mode.

MUFF 1- Sets the overall output level for the Double Muff in either mode.

MUFF 2-Sets the output level for the first Muff in Double mode. In Single mode this knob is inactive.

STATUS-If on, the unit is engaged. If off, the unit is in True Bypass mode.


Plugging into the input will activate power from the internal 9-volt battery or external battery eliminator. The input cable should be removed when the unit is not in use to avoid running down the battery.

In Double mode, the Double Muff has very high maximum gain, requiring that pickups and cables be well shielded and properly grounded to avoid excessive hum.

The small jack on the back of the Double Muff is for a 9-volt battery eliminator capable of delivering 100mA of current. The unit’s battery may be left in or taken out when the eliminator is in use.
