Hi guys, just some quick explanations: my Jazz bass is "quite new", built in april 2010, I have it since november 2010. A buzz started some months ago at the upper area of the neck, over 9th or 10th frets, annoying when I slap or play strongly in that area. I've heard that bolt-on neck's wood can inflate at the neck join: moisture issues? I had some flood damages some months ago in my home, so I'm naturally thinking about this. De facto, I thought that removing last frets and levelling the fingerboard would be an option. Any advices ??
