I completely restrung the g-string, so I dont think there is anything in the slot. I dont have a capo, so I cant try that. And for some reason, it mostly happens when I play powerchords, so I thought it was my finger position, but its never happened before. Its definately hitting a fret, and I even raised the action to a level no player would dream of trying to play with, and no luck.
You took all the strings off right? How long did you leave them off, because you might just need to let the neck readjust to the tension for a couple of days, and your buzz could go away. There might not be enough relief now, since I'm assuming you took all the tension off the guitar by taking the strings off for some time. Do you have a straightedge to check the relief? Sometimes when you string and restring you can introduce a kink in the string that will cause a buzz. I'd definitely put some new strings on it.
Yeah, I snapped my high-E, so I replaced them all already. Luckily I had a few spare sets. Anyhow, I only had the strings off for maybe an hour, tops. I did check the relief, its exactly where it should. Thanks for the help so far.
