Hey guys, need some advice. I just picked up a PRS SE Zac Meyer ( don't know who he is) from a friend who doesn't play but had this guitar. Upgraded USA '57/08 pickups, CTS Pots and some other upgrades were already done to the guitar. The guitar played great, sounded great and the price was really good so I grabbed it. Anyway, I decided to re-string and polish the frets because the strings were still the original according to my friend. Here's where it goes south- now the g string is dead up and down the neck. Sounds all muffled, no ringing. I blame it on polishing the frets, and I can't figure it out. I nut-sauced the nut and the bridge, and still no luck. Driving me nuts. So did polishing the frets do this? Is the nut or truss rod now out of whack? Your advice would be appreciated . Thanks!
