User Manual

INPUT Jack – This ¼” jack is the audio input to the Nano Bass Big Muff.
The input impedance presented at this jack is 110 kΩ.
AMP Jack – This ¼” jack is the audio output from the Nano Bass Big Muff.
When the Nano Bass Big Muff is in True Bypass mode, the AMP jack is
connected directly to the INPUT jack.
9V Power Jack – The Nano Bass 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 Bass Big Muff has a current draw of
approximately 4mA at 9VDC.
We recommend the Electro-Harmonix US96DC-200BI
9.6VDC/200mA 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 Bass 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.
