electro-Harmonix NANO BIG MUFF PI Distortion/Fuzz/Overdrive Pedal
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.
CHANGING THE BATTERY
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.
