OK - New here but not new to PRS. Love (just love) my 2008 McCarty Korina. My 4th string (G) keeps breaking about every 30 days or so. I am a string bender and as you know the G and B are great strings to bend into unison.

Can I (very finely) file the edge of the groove where the G comes out of the tailpiece or am I really messing with my intonation and destroying the tailpiece? Help please!
