It have more bass than the NYC one. For me it sounds better. This is a piece of history. EHX sure did a big mistake when they stopped the Russian labeled series and called green muff a bass one. It is confusing.
everything you hate about the big muff now with extra low end swamp, less midrange and a really unreliable switch! I used this as a bassist for years though and loved that sound, but the switch gave out... my black Russian never sounded as full for bass.
