Before I received this DGT, it had been out on the showroom floor for some time and had the dings to prove it. I got an exceptional deal on it so I didn't mind, but a couple of the tuners were stiffer than they should be. I assumed that they must have impact damage, so I went through them looking for damage but found none. I've installed and rebuilt quite a few tuners before and understand the workings and adjustments, but these remain stiff no matter what. I attribute it to a manufacturing tolerance issue. The other guitars I have with these tuners feel correct.
I know I could have sent the guitar back to PRS for repair/replacement, but I decided it wasn't bad enough to bother with. I've seen a couple of other mentions of this before, so my guess is they might have had a bad 'Friday' batch of tuners sneak through with a gear lash issue.
Bottom line is I have no doubt that PRS would take care of this if anyone finds it too troublesome.
