Production sat roughly in the early 1990s after Electro-Harmonix returned via Russian factories. The circuit matches the contemporary Red Army Overdrive aside from cosmetics, with Volume, Tone, and Distortion (sustain) controls and a less mid-scooped voicing than many USA Big Muffs of the 1970s.

Players favour these units for bass-friendly low end and smoother mid presence that can cut a live mix better than deeply scooped NYC voicings. Unit-to-unit parts variance is common on these hand-built Russian boxes.

No current Electro-Harmonix product page exists for this SKU. Later Green Russian reissues and the Sovtek Deluxe Big Muff Pi reference the same Civil War / tall-font Russian circuit family, but this page covers the vintage Civil War-era pedal itself.
