To me, the ding is nothing. If you play the guitar it'll have a little buckle rash, it'll take a few bumps. So I think I'd try to determine if this is a really great guitar, and if it is, the I'd just keep it. 50 bucks or 100 bucks is just... nothing here, to me. You could get the next guitar in your hands and it might not have a ding, and it might play kinda crappy or the neck might not feel so good... if you have a winner on your hands as a player.... don't let it go just because of some silly cosmetic thing. It's real nice of Sweetwater to make the offer they did, I'm impressed. But I'd ignore it IF the guitar you have is real sweet.
