I've got a PRS SE Custom 22 (discontinued, to my knowledge) that I bought off the floor at Sam Ash about 4-5 years ago. Plays excellent despite the fact it has a few dings here and there, otherwise an excellent guitar.

For whatever reason, I've noticed this on both sides of the base of the neck/fretboard for the first time

Part of me wants to say it's a finish crack (on one side at least) because I did not see any cracks in the wood connecting to the fretboard, but I'm not sure. I mean the thing plays fine, should I even worry?
