| As for the Russian vs the Bass big muff, I have both and when I got the bass version I pretty much stopped using the other. However, what you need to do is try both.
But what I can tell you is that I often play guitar through the bass big muff. It's a nice effect, but it doesn't sound like a muff, it sounds more like an overdrive. I use the mode where it blends the original signal in, and then chords come out distorted and single strings come out clean.
