Last night I broke an "A" string, it was only two months old. So I figured I'd just replace it out of a set I had from last year - until I noticed that "A" string was missing too. Hmm, I broke the "A" last year? Wonder if my bridge has a spur on it? Wait a minute - I was using the other bass last time! Anyone else have this problem? They were both Powerbass 5 string sets. This first time I was playing with the metal band, and just figured, ok, I play pretty hard, it was bound to happen. But last night I was jamming with the rock band, and not playing hard at all. I really love these strings, but at the price, I would hope they'd hold up better.
