Recently my Ray34's E string started rattling. It is very distinct from fret buzz, I think it may be the intonation screw, when I loosen it, it just comes out the back of the bridge and the rattle gets worse, when I tighten it, the rattle goes away for a bit, but quickly returns. Has anyone else had this problem? Also, where would I get a stronger intonation spring from? I'm using heavy Bass Boomers(.115 -.050), so that is probably contributing to my problem, but I really like these strings.
