Thanks for all the praise! Going to try her out in a band setting on Sunday - really can't wait!
I have one gripe with this specific bass though: my luthier said that the neck can't handle Ernie Ball's Super Slinkies (100-80-65-45) so he put in 95 and 40. He also said that the truss rod is one of the worst kind he's ever seen because it doesn't add support to the high fret area causing a slight bow there. Thankfully the smaller gauge strings are more than playable and he set up the action ultra low so it's a wonderful thing to play.
Almost any bass with trussrod access at the head has the same support setup, your luthier should know this (on Fenders it's called the ski-ramp effect, but it can happen to almost any bolt-on bass with the adjustment in the head). Also, he may not realize that there is a microtilt adjustment at the heel of the neck that could be messing up his adjustments.
