Exceptionally clean, all-original Electro-Harmonix V8 "Small Box" Black Russian Big Muff Pi distortion/sustainer fuzz pedal, manufactured in Russia during the late 1990s/2000s Sovtek production era.

​This small-box variant delivers the unmistakable, crushing low-end punch, thick sustain, and aggressive upper-mid gain that made the Russian Muffs legendary for guitarists and bassists alike.

​Highlights & Condition:

​Cosmetics: In excellent vintage condition with crisp, fully legible yellow screen-printed faceplate graphics ("BIG MUFF \pi" and Cyrillic "Сделано в России") with minimal wear.

​Hardware: 100% stock and complete. Features the original black chicken-head pointer knobs, top-mounted input/output jacks, original red status LED, and factory footswitch.

​Bottom Panel & Battery Door: Includes the complete bottom plate with the original battery compartment cover and screw intact—a part frequently missing on these Russian units.

​Functionality: Fully tested and 100% operational. All three potentiometers (Volume, Tone, Sustain) sweep smoothly, the footswitch engages cleanly, and the circuit delivers huge, quiet sustain without excessive noise.

​Modifications: None. Unmodified, original Russian circuit.
