Don't bang on it. :D

Seriously, I am sure that the gear-heads here at GT will have some good insight for you. This is an acoustic, right? If it's electric, you might have to adjust your bridge height a little on that string. Have no idea on an acoustic. Sorry. (Had to make the joke though...can't help myself....it's an illness....)
