I'd suggest you drive up to Greensboro and look up Bob Beerman. Here's his
link.
I know it's a bit of a stretch to drive from Charlotte up to Greensboro, but you'd be taking it to a BASS luthier, instead of a guitar tech in a store specializing in Mexican made stratocasters.
Bob is a great guy. If you consider doing it, call and make sure he's available. I'd say this is one of the best options for you to have a good appraisal of the bass you are considering buying. And be sure to offer to pay him a bit for the service he can provide for you.
I hope this helps.
