Ok on my Les Paul when ever I play the A string it gives this awful rattleing sound. It does this when I play it open up to about the 12 fret.

any help is appreciated
In that case, it could be the saddle at the bridge, then. I'm assuming this isn't something obvious, like the pickups being raised into the strings.
stuff some foam down around your saddles. i had this problem with my seven string recently and i foamed the shit out of all the saddles and its all better. no more rattaling
