POCKET METAL MUFF

- DESCRIPTION -

Congratulations on your purchase of the POCKET METAL MUFF! You now
have the instant classic thrashing tone of the Metal Muff in the palm of your
hand.

- CONTROLS -

DISTORTION CONTROL – adjusts the amount of input gain.

VOLUME CONTROL – sets the output level.

SCOOP TOGGLE SWITCH – provides two settings of attenuation in the

middle frequency range. In the up position, the mid attenuation is high. In
the middle position the mid attenuation is low. In the down position there is
no mid frequency attenuation.

FOOTSWITCH – Selects whether the POCKET METAL MUFF is engaged or
bypassed. The corresponding LED will be lit when the pedal is engaged, and
dark when bypassed.

INPUT Jack – This ¼” jack is the audio input to the POCKET METAL MUFF.

OUTPUT Jack – This ¼” jack is the audio output from the POCKET METAL
MUFF. When the POCKET METAL MUFF is in Bypass mode, the OUTPUT jack
is connected to the INPUT jack through a buffer.

- OPERATION AND WARNINGS -

Power, from the internal 9-volt battery or external battery eliminator, is
activated by plugging into the input. The input cable should be removed
when the unit is not in use to avoid running down the battery. The input
impedance presented at the Input Jack is 1Mohm. The output impedance at
the Output Jack is 600 ohms.

The barrel connector on the front of the POCKET METAL MUFF is for a 9-volt
battery eliminator capable of delivering 100 mA of current. The inner ring of
the 9-volt battery eliminator must be negative, the outer ring positive.

The unit’s battery may be left in or taken out when the eliminator is in use.

To achieve its biting distortion, the POCKET METAL MUFF has very high
maximum gain. This requires that both the pickups and cables be well
shielded and properly grounded to avoid excessive hum when high sustain
control settings are used.

To change the 9-volt battery, you must remove the 4 screws on the
bottom of the METAL MUFF. Once the screws are removed, you can
take off the bottom plate and change the battery. Please do not
touch the circuit board while the bottom plate is off or you may
damage a component.

The optional 9V power supply from Electro-Harmonix is US96DC-200BI
(same as used by Boss ™ & Ibanez™) 9.6 volts/DC 200ma. The barrel
connector on the front of the POCKET METAL MUFF is for the 9-volt battery
eliminator capable of delivering 100 mA of current. The inner ring of the 9­volt battery eliminator must be negative, the outer ring positive. The unit’s
battery may be left in or taken out when the eliminator is in use.
