I recently purchased a Squier Vintage Modified Jazz fretted model off Craigslist, and after I got home with it, I noticed that a small piece of duct tape was placed around the A-string where the string went through the nut. I was cleaning up the bass, so I took that duct tape out, and now the string buzzes whenever I play an open A. I checked out all the frets, and I am pretty sure that the slot is too wide on the A. I'm getting some new strings to install to see if that clears up the buzz, but I don't really want to go up in string size to just clear this up. I've been reading on here that there's pretty much two options ... fill in the slot and re-cut, or install a new nut. I don't mind doing a little work on the bass, so I was trying to find out any recommendations on doing either of these. Any other suggestions? Thanks!
