Ahhh the sleeper muff.

Excellent working condition. Added 9v dc power jack, which cuts battery ... Allows typical 9v power supply use, instead of a battery. Overall very good condition with only some minor scuffs on the sides.

Get those crazy muff tones from mild to wild. Great for guitars and basses.

Here's an online review:

"Version 7 “CIVIL WAR” BIG MUFFS (Russia circa 1991) – Identical to the second edition Red Army Overdrive, just different graphics and colors. Sort of a mix between the V1 and V3 Muffs, but with a fatter bottom end, brighter and less scooped mids, and less gain. It was very dark and bassy, but with a smooth and clear mid range, and a very musical clarity. Those mids were still scooped out like a typical Big Muff, but the Sovteks had more mids than vintage USA models, so they stand out in a live band mix slightly better. They are noticeably smoother and have less grit than the later Green Russian and Black Russian Big Muffs, which is probably why they are the most favored and desireable of all the Sovtek Big Muffs. They are a favorite of bass players due to the low gain and huge, bass friendly bottom end they produce. The bass and treble of the tone varies slightly from unit to unit. Listen to Pink Floyd’s Pulse live album for some great examples of lead tones using this pedal. The Black Keys and Sonic Youth have other examples of this sound."

Please note, there's a little lint on it in the photos.
