Electro-Harmonix Nano Big Muff Pi Instruction Manual

NANO BIG MUFF PI

Congratulations! You have just purchased the finest harmonic
distortion-sustain device developed to date for the electric guitar
player, now in a very compact pedal. The Nano Big Muff Pi works
and sounds identical in every way to our classic Big Muff Pi. We
took the Big Muff circuit and simply shrunk it, without any change
to its rich, creamy, violin-like sustaining sound.

-OPERATING INSTRUCTIONS-

SUSTAIN CONTROL — adjusts the amount of sustain and distortion.

TONE CONTROL — provides a range of sounds from high treble to deep

bass. As you turn the knob clockwise the treble increases and bass
decreases.

VOLUME CONTROL — sets the output level.

Footswitch & Status LED - When the LED is lit; the Nano Big Muff effect

is active. When the LED is off, the Nano Big Muff is in True Bypass mode.
The Footswitch toggles between effect and bypass modes.

INPUT Jack – This ¼” jack is the audio input to the Nano Big Muff. The
input impedance presented at this jack is 130 kΩ.

AMP Jack – This ¼” jack is the audio output from the Nano Big Muff.
When the Nano Big Muff is in Bypass mode, the AMP jack is connected
directly to the INPUT jack.

9V Power Jack – The Nano Big Muff Pi is powered from a 9V battery or
you can use an optional 9VDC AC Adapter capable of delivering at least
25mA to the 9V power jack, such as the EHX9.6DC-200. The AC Adapter
must have a center negative plug. The battery may be left in or taken out
when using an AC Adapter. The Nano Big Muff has a current draw of
approximately 3mA at 9VDC.

We recommend the Electro-Harmonix US96DC-200BI AC Adapter to
power your Nano Big Muff Pi.

To change the 9-volt battery, you must remove the 4 screws on the bottom
of the Nano Big Muff Pi. 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 risk damaging a component.
