After three restrings, the A string from a set of Rotosound Jazz bass flats (purchased on Saturday) snapped at the curly Q. Needless to say I'm disappointed in the quality of these strings. I planned for this set to last years, but the wire at the tuner side is so thin that it couldn't handle being strung up more than once. I have plenty of string ends lying around - is there a way to lengthen the string by grafting? It's way too expensive to buy a single string and this is a brand new set of flats. edit: Thanks to Rotosound USA, a replacement A string is on its way.
