In the early 90's, I had one of those Sovtek Russian Big Muffs that came in the wooden box with Russian on it. A very striking memory at the end of the Cold War era! I really liked the sound of that one. I am aware that there are about 1,000 Big Muff types these days, and I don't want to sort through the pages and pages of discussion. So I'd like to pose this to you experts: Which is the nastiest, most raw new-production Big Muff type pedal? I don't care if it's EHX or even Chicago Stompworks (I actually love CSW's stuff). I just want it to be approximate to that raw Big Muff-type sound that has fueled Dan Auerbach's sound for a while now. So which one is it? Thanks!
