The ultimate metal distortion pedal. Three powerful EQ bands sculpt the
mids and 6 controls shape the sound precisely for your groove from
slithering mercury to lead belly blast furnace dross. Its unique Top
Boost adds serious bite with its own control knob and footswitch so you
can kick it on for searing leads.
Quick Specs
- High input impedance buffered bypass
- Output volume and master drive controls
- 3-Band EQ: bass, mid and treble
- Footswitchable Top Boost with separate control knob
- Tough and compact die-cast chassis
- 9-volt battery included
Electro-Harmonix gave its total effort to design the best heavy metal
pedal ever built. The Metal Muff utilizes three powerful EQ bands,
including a midrange control designed for perfect contouring and
beautifully sculpted mids. The Metal Muff offers commanding bass and
defined high end-coupled with user-controlled distortion from
pinched-edge to totally crushing-making it a heavy metal gold mine.
- CONTROLS -
DISTORTION CONTROL - adjusts the amount of input gain.
BASS CONTROL - provides up to 14dB of cut and boost in the bass frequency range.
MID CONTROL - provides up to 15dB of cut and boost in the middle frequency range.
TREBLE CONTROL - provides up to 10dB of cut and boost in the treble frequency range.
TOP BOOST CONTROL - provides an extra ‘bite’ by boosting a narrow
band of high frequencies. When Top Boost is inactive, the Top Boost
control has no effect.
VOLUME CONTROL - sets the output level.
TOP BOOST FOOTSWITCH - Engages the TOP BOOST feature of the METAL MUFF. The corresponding LED is lit when TOP BOOST is engaged.
BYPASS FOOTSWITCH - Selects whether the METAL MUFF is engaged or
bypassed. The corresponding LED will be lit when the pedal is engaged,
and dark when bypassed.
INPUT Jack - This 1/4” jack is the audio input to the METAL MUFF.
OUTPUT Jack - This 1/4” jack is the audio output from the METAL
MUFF. When the 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 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 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 (tm) & Ibanez(tm)). 9.6 volts/DC 200ma. The
barrel connector on the front of the METAL MUFF is for the 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.
