Ok here's the deal. I go through strings like nothing and it is almost annoying because I always run out of replacements at the wrong times. I do have a pretty heavy attack but I also bend the living crap out of my strings. My question: is there something that could be wrong with a guitar that would make strings break easier like a sharp spot on the bridge? Also heavier strings should last longer that lighter ones right? Btw I play on 12-50 ernies
