-I always start below the pitch and tune up.... My understanding regarding tuning issues is that any number of things can be the cause. Here are just a few:
- uneven frets
-improperly adjusted neck can cause intonation and tuning issues
-strings can and sometimes do get hung up at the nut or bridge if the slots aren't cut properly.
I often wonder if something happened during shipping...
I'm not a heavy or hard player..definitely not what anyone would call a shredder by any stretch of the imagination...I actually have a fairly light touch in comparison to many players and IF I do bend a string, it might be a 1/2 step if even that much. More and more I'm beginning to think it could be the fact that the headstock and tuners are resting against a wall overnight..although in a gig bag and the G string tuner is getting pushed, or moved.
Think I will try an experiment and leave it out of the case tonight and not resting against a wall...or just leave it in the case and not leaning against the wall but rather lying flat.
Also not sure if temperature and or humidity plays a part here...I know those things can and most often do reek havoc with wooden instruments..and for electric guitars the neck and frets especially can become affected.
I have seen tons of UTube videos and read several articles about how it's always the G string that goes out of tune....and usually remark about it's often the nut. Who knows....
The odd thing is, once out of the gig bag, re-tuned and if the guitar sits out all day it's fine....however the next day if I'm not playing one of my other guitars and reach for the PRS, simultaneously I reach for the tuner cause I KNOW I will need it !
Anyway...just airing some thoughts. You know, process of elimination.
Maybe one day I'll make the 2.5hr o/w trek to John Mann's Guitar Vault who is a dedicated PRS dealer and see what he says about this issue AND check the tone knob which has zero resistance as compared to the volume... OR to a luthier I once went to a bit closer to home. It's not a major thing re-checking the tuning daily, just has become a bit of a mystery that's all...
