Upton Basses

[Michael Case]

I don't wanna come off the wrong way, but I need to ask this question for my own satisfaction. If Upton has these basses built in a factory in Romania and all they do is varnish, add fingerboard, bridge, soundpost, end-pin, and set-up. What makes these basses so different than any other factory bass (hybrid or carved) in the same price range set-up by the luthier of your choice.

I'd like to know because I'm sort of considering a Professor bass or saving a bit more scratch and getting a NS LaScala Hybrid or carved if possible.
