I am new to PRS and finally pulled the trigger and am enjoying my first PRS guitar. It's an excellent condition Vela. The neck needed an adjustment, so I adjusted the truss rod and it fixed it. Then a few days later, it relaxed again. I did my third small adjustment late yesterday and so far is holding. I bought the guitar from Guitar Center and it had to be shipped. I was wondering if PRS truss rods come loose like this (during shipping) or maybe I have a bad neck? Any advice is welcome. I LOVE the guitar, but don't want to buy a new neck and pay for the labor to install. (I could just go and buy a new guitar then.) My understanding is it;sz not under warranty because I am not original owner.
