-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.
