electro-harmonix Nano Bass Big Muff Pi Overdrive Pedal
Congratulations! You have just purchased the finest harmonic distortion-
sustain device for the electric bass guitar player, now in a smaller
enclosure: the Nano Bass Big Muff! Please review this manual to learn the
unique potential of this pedal.
The Nano Bass Big Muff draws its roots from the legendary Sovtek battle-tank
green Big Muff Pi manufactured in the ‘90s as well as from the original
Electro-Harmonix Big Muff Pi from the early ‘70s. These Big Muffs are often
employed by bass players to thicken up their sound or to give them an over-
the-top low-end growl. The Nano Bass Big Muff takes the best characteristics
from both of these classics and employs sonic elements that were specifically
designed for your bass.
OPERATING INSTRUCTIONS
SUSTAIN Knob — adjusts the amount of sustain and distortion.
TONE Knob — provides a range of sounds from high treble to deep bass. As
you turn the knob clockwise, treble increases, and bass decreases.
VOL Knob — sets the output level of the distortion effect. When the
toggle switch is set to DRY, the volume knob has no effect on the output level
of the dry signal.
DRY Toggle Switch — when set to DRY mode, the original dry signal present
at the input jack is mixed with the output of the distortion circuit. The
level of the Dry signal is constant and will not change as you turn the Volume
knob up or down allowing you to set the level of the distortion effect against
your dry signal. Flip the DRY switch to the left, away from the DRY label, to
mute the dry signal; now you will hear only Big Muff distortion.
Footswitch & Status LED — When the LED is lit, the Nano Bass Big Muff
effect is active. When the LED is off, the Nano Bass 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 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.
