You got a problem? Did you buy a carton of strings or several sets from the same stock. I have had 1 string consistently break out of several sets of strings and they all came out of the same carton (gross) I bought. I would just go buy several single strings to get me thru the carton. Unless you still got the recpt. then you could try and return them. Heavier gage is a good idea anyway but unless your a neanderethall man you still shouldn't break strings. Even then do you realize what it takes to break strings. Usually it is wear or a defect in the guitar. which brings me to my last solution. Look closely at the string where it breaks. If it is breaking at a point where the string bridges the guitar or at the nut, you probably need to get it to a tech and see if there is an edge that needs some filing or buffing. If its breaking out in the middle or behind the nut or bridge and is consistant that is probably a bad batch of strings. Evenif you bought them 1 set at a time most stores stock them this way. :cool:
