@BassicJazzy @crazycloud @mickebas thanks all for the tips. I've done quite a few of my own setups on many guitars and a few of my basses but this one was disturbingly tough to budge. Never faced any issues with my 2 other basses with roasted necks one of which also has a truss rod wheel (Sterling StingRay & Sire P5R). That being said, my luthier (who also thought it was terribly tight) took care of it and got it moving again after taking the neck off. We don't get much weather variation in humidity here in Kuwait so once it's settled in hopefully it won't need much adjusting anyways. Other than that, I'm really loving this bass now 
@Testing123 yes after my luthier got it moving again it's not stiff anymore and easy to adjust now and hopefully it stays that way in the future.
@Bassplayer1586 thanks for pointing that detail out, didn't pay attention to the fact that they're “luminescent” side dot inlays not "Luminlay". You're absolutely right, it's right there on the official spec page but the photo they have there looks nothing like mine (barely glowing after sitting in a bright room for hours). Makes my idea of just coloring them white even better now
Beautiful bass by the way
