Well, my new NF3 arrives tomorrow.
I will report back on the tuning stability.
Don't want anyone to get me wrong, I've owned five PRS guitars now (all USA versions, not the SE's) and if that doesn't tell you I like them very much, then nothing will.
At the risk of extreme redundancy, I just think a guitar of this caliber really should be more consistent when it leaves the factory.
Regarding the Bigsby equipped Reverend mentioned by Egads, I've never used one of those personally.
Reeves Gabrels was showing off his new Reverend at the NAMM after show party and his stayed in tune through some very harsh treatment with a Bigsby tremolo.
He told me about the design process and a few tricks Joe Naylor applied to his newest model and that it added to the tuning stability.
The three Rev's I own have Wilkinsons.
