Matthew, Once again I will quote the great Yogi Berra. " You can observe a lot by looking. " It's typical for the coil on the replacement string to be somewhat different than the original. Also the replacement string will typically just look different. Either more shiny, or have a different style ending of the wrap , or the length of the wrap will be out of line with the others or indeed the core will deviate or the tuning pin will be at a different height or the loop at the hitch will be different. You have 40 or so other strings and several criterion for comparision. I'll bet with your keen observational powers you will detect the string to replace from across the room .Boldly go forth young man . I hope that this post hasn't been upsetting and you are welcome in advance.

My guess is that someone replaced it with a universal and, hence, the tone is not matching, causing the "out of tuneness". I vaguely remember hearing one time how to tell the difference between a universal string and a duplicated one. I think it had something to do with the core wire. The universal being hexagonal? Can someone please tell me how to tell? If this issue is the case, I want to make sure I remove the right one! Thanks in advance!
