So I've had more time with the Black Russian. What a sick a** muff! I don't think I'll ever have a need or desire to look further. The bottom end is massive on it and it fills space out wonderfully. It's not as articulate and clear as say my wood chipper but that's mainly because I keep the tone dialed back to 1 o'clock or so. I'm really happy I ended up getting one. And that I made the decision to delve into muff fuzz again. I disliked muffs for years and the Black Russian has made me really happy.
