So has it, or has it not, had a proper setup? your first post says you are going to take it for a setup, and your last post says it HAS been properly set up. Confusion reigns!
From the factory, cheaper basses are just not "setup". "Setup" means making it playable for YOU and probably replacing the crap strings that will come on a factory bass with something better.
So if it HASN'T been setup yet, then your visit to a good luthier will probably make a difference.
If it HAS been properly setup already, then either the bass is just a dark bass, or your luthier hasn't done enough on it yet, or you haven't paid enough for the setup, or any of a hundred other things. Or you might even need to adjust your expectations.
Noob, you're not giving much away, so its really difficult for anyone to help you with useful information. What bass did you get? How much did you pay? Where are you? What strings are on it? (show us a photo) What did you play before you had this one? yada yada yada
