Re: 2010 S570DXQM... Did I mess up?
Depends on your definition of messing up. The guitar you bought will probably be nice enough, but for $650 on the used market, anyone here could probably point you toward 50 used Ibanez that are significantly better in terms of quality hardware and playability than what you'll get from a new S570.
Just my personal opinion, but if it's not too late to cancel your order, I'd do so and look for a used S540 (if the S is your thing).
Start by looking in the classifieds here, as there are some super nice axes for sale.
