I got a $50 dollar GC credit for my birthday about 2 months ago, so I picked up a russian big muff. I plugged it in, turned it on, started playing (duh, what else was i going to do? make a sandwitch?). it sounded good, but I wasn't getting the Matt Sharp sound I was shooting for. I was going to return it, as it took out alot of the lows and just plain sucked switched off, which eliminated any use I was going to have for it. I think Robert Keeley, who lives 20 minutes away from me, could mod it for like $20. I can either: Return the big muff, and buy some crap that I don't need. (strings or a 3" strap that I crave) Or Pay to get the bass/true bypass mod. And I'm torn between the two desicions. Has anyone ever used a modded big muff? Did it sound good?
