I'm new to guitars and everything, but I recently got a Peavey Raptor and it was fine at first, but one time I tuned it and it developed a buzz in the bridge/body whenever I play a G note. It's worse on the open G string, but if I play a G anywhere else there's still a bit of a buzz. This isn't heard in the amp, but I'd like to fix it somehow if anyone has any ideas?
