I have a Gibson firebrand, and I'm having trouble with my "a" note 2nd fret on the g string. For some reason that note is always sharp!? I checked the other notes on the string, and they are all pretty good. I had the frets checked and cleaned up about 6 months ago, and this seemed to solve the problem, but now it is back again already.. I've been having to tune the g string a little flat to compensate, but there has to be a way to fix this!

HELP!! :eek:
