I am curious. Way way way back in like 72 was the last time I played a Big Muff, so it has been a while since I heard them. Recently a friend of mine lent me his Russian Big Muff. Dont know when it was made, he said he bought it used about 5 years ago. Has no AC, batteries only, Dark (army) green. Anyway, plugged it in, and for my ears it sounded pretty good, but "tame" from what I remembered the BM to be. My question is, are my ears just not remembering the old BM correctly? Or is the Russian model more tame than the US? I thought I remembered the old (US made) BM to be this loud super fuzzy almost out of control sound. This was cool, but not super fuzzy, seemed to be more of a distortion than a fuzz. So could somebody tell me the difference between the Russian and the US and if the sound has changed over the years? Thanks guys!
