UPDATE 3/14/2017 My dealer confirmed that it is likely tiny air bubbles which is covered under warranty and should take 2-3 weeks at PTC. I don't have to send it in right away. Unless it bothers me while playing, my dealer suggests waiting up to 6 months (unless it gets much worse) as most issues seem to surface in the first 6 months of a guitar's (playing) life. I didn't even realize this falls under lifetime warranty. Amazing.
