Nano Metal Muff
with Noise Gate
Congratulations on your purchase of the Nano Metal Muff, a pocket-sized offering of
EHX’s classic Metal Muff. The Nano Metal Muff utilizes three powerful EQ bands and a
newly added noise gate to tame unwanted noise and hum between riffs. The Nano
Metal Muff offers commanding bass, sculpted mids, and defined highs coupled with
user-controlled distortion from pinched-edge to totally crushing—making it a true
heavy metal machine.
CONTROLS
DIST Knob – Adjusts the amount of distortion and saturation. Turn clockwise for
more saturation.
GATE Knob – Removes unwanted hum by adjusting the noise floor threshold. The
gate mutes the OUTPUT jack when the signal at the INPUT jack is below the threshold
setting of the GATE knob. As GATE is turned clockwise, a louder guitar signal at the
INPUT jack is required to unmute the OUTPUT jack. Set GATE fully counter-clockwise
to disable.
Setting the GATE knob: start with GATE fully counterclockwise, DIST above noon, and
your guitar volume at max, you may want to hold the strings so they don’t ring out.
Slowly turn GATE clockwise until the Nano Metal Muff mutes. Now turn GATE a little
further clockwise and then test it. If you have to play with too much force to unmute
the gate then turn GATE a little counter-clockwise. If you want the gate to act more
quickly at the end of notes, turn GATE further clockwise.
GATE LED – This LED lights when the internal gate mutes the output signal. When
the GATE LED is off, the signal is allowed to pass through to the output jack.
VOL Knob – Sets the overall output level.
BASS Knob – Provides up to 14dB of cut and boost in the bass frequency range.
MID Knob – Provides up to 15dB of cut and boost in the middle frequency range.
TREBLE Knob – Provides up to 10dB of cut and boost in the treble frequency range.
BYPASS Footswitch & STATUS LED – Toggles the Nano Metal Muff between effect
and buffered bypassed. The STATUS LED lights when the pedal is engaged.
