Electro-Harmonix Green Russian Big Muff

Back by overwhelming demand... in a mini package! The cult classic Green Russian Big Muff first shook the ground in the mid-1990s. Since then it has been heralded by guitarists and bassists for its devastating low-end and unique sludge and sizzle. The Green Russian Big Muff creates a huge tone that is all its own, but is undeniably Big Muff.

This is an authentic reissue of the legendary Green Russian Big Muff Pi. We should know, we built the original. Now you’ve got the exact same sound beloved by guitarists and bassists alike at your fingertips, but in a smaller, more pedalboard-friendly enclosure. So, throw off your chains and unite with the finest harmonic distortion-sustain device ever made.

OPERATING INSTRUCTIONS

VOLUME Knob

Use the VOLUME knob to set the output level.

TONE Knob

Adjust the TONE knob to explore a range of sounds from high treble to deep bass. Turn the knob clockwise to increase treble and decrease bass. Turn the knob counterclockwise to increase bass and decrease treble.

The SUSTAIN knob adjusts the amount of sustain and distortion.

Footswitch & Status LED

Use the footswitch to toggle between effect and bypass. The Green Russian Big Muff is active when the LED is lit. When the LED is off, the pedal is in true bypass mode.

IN Jack

Plug the output of your instrument or another effects pedal into the ¼” IN jack. The input impedance presented at this jack is 130kΩ.

OUT Jack

Connect the Green Russian Big Muff’s ¼” OUT jack to the input of your amplifier or another effects pedal. When the Green Russian Big Muff is in bypass mode, the OUT jack is connected directly to the IN jack. The output impedance is nominally 25kΩ.

POWER!

Powering the Green Russian Big Muff Pi

The Green Russian Big Muff Pi may be powered from a 9V battery or an optional 9VDC AC Adapter such as the EHX9.6DC-200 or any Boss® or Ibanez® style AC adapters capable of delivering at least 30mA. Plug the output of the adapter into the 9V power jack located at the top of the pedal. The battery may be left in or taken out when using an AC Adapter. The current draw is approximately 2.2mA at 9VDC.

Please Note: Using the wrong adapter or a plug with the wrong polarity may damage your Russian Big Muff Pi and void the warranty.

Changing the Battery

To change the 9V battery, remove the 4 screws on the bottom of the Green Russian Big Muff Pi. Take off the bottom plate and change the battery. Avoid touching the circuit board while the bottom plate is off. Replace the bottom plate and screws.
