So, the old Ibanez PL2550 that I picked up has been gradually worked on. I got new nut pads for it, and lock blocks for the bridge, along with a trem arm. It's playable right now, though still missing a couple screws, and not exactly clean or perfect. Some day I'll get a whole new bridge for it, because this one is pretty beat up and has an oddball part or two thrown in.
The main issue right now is that my G-string buzzes when open and rings out slightly flat. If I tune it to a fretted note, it's in tune across the board, except open (which buzzes). I'm assuming, then, that there's something wrong with the nut? Will this require a new nut entirely?
