Noticed my E string was buzzing a lot, so I tried to figure out what was wrong with it. I tried raising the string height, but that didn't work. Then I noticed the slot in the nut is about 1 1/2 times the width of the string, so I'm pretty sure that's the problem. Also, it sounds like the buzzing is coming from that end. I don't think a new string/strings is an option because the hole is really wide, so it would take a really fat string... Does it cost much to get a new nut fitted, or is it easy to do it yourself? I don't know what size the strings are or what kind of nut to get, so should I take it to the shop and see what kind to get?
