I received this Green Russian Big Muff for repair not too long ago. This exact pedal was mine for a long time before I moved it on. It has some cool mojo with its chipped tank exterior and big silver push-button on/off switch. This pedal was the inspiration behind my cubisteffects T-34 Bass Big Muff mod as it holds so much of the guitar’s bass frequencies while thickening up with its characteristic smooth fuzz tone.
I replaced the in/out jacks with some 21st century Neutrik jacks. I also printed up some new Russian-esque Volume, Tone and Sustain labels as the originals had been chipped off many moons ago. But once inside I couldn’t resist taking a few pics for old times sake. Note the original Russian capacitors and transistors that give the pedal its unique, and sought-after, tone.
