So you know how some strings have that colored string wound around the end where it makes contact with the tuning nut. well I'm about to do a string change on the old fiver and was curious if I could just put my own colored thread/string on a set of strings that doesn't have any. I imagine it's just to protect the strings, but I wasn't sure if maybe there was another purpose for this colorful addition to otherwise boring old silver strings than just to look cool?
