What we say:

Before Electro-Harmonix began reissuing the Big Muff Pi fuzz from their NYC headquarters, theBig Muff was being made in Russia from old tank parts! These Russian Muffs (stop it) had a slightly different tone: more low end, more aggressive and less smooth. This pedal was essential to the whole Sludge/Doom movement and E-HX are honouring its reputation with this nano-enclosured tribute!

This new nod to the mid 90s Russian model sounds exactly as you'd expect: big, abrasive and containing a large degree of 'woof' like all great Big Muffs have! They've kept the army-green colour scheme too and incorporated True-Bypass switching to improve the quality of your signal chain when the unit is disengaged. We welcome the return of this old war hero!


Kongratulations Komrades!
You now have in your possession the 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.

Use the VOLUME knob to set the output level.

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.

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.

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.

I am not a great fan of fuzz pedals but this one is so versatile and sounds really good. Just need to set it right for the tone you want and have a slightly broken-up amp. Not so good with a real clean amp.

Great fuzz sounds that work in a lot of different ways. Very powerful when engaged. The low end is retained beautifully even in the typically high settings also. A go-to fuzz pedal. Powerful for a small piece of equipment.

Great product. Was after a great sounding Muff. Was excited to see the Green Russian had been re-issued. Compact and lightweight.
