I just purchased a MIM fretless jazz bass(it was a floor model) at guitar center. I noticed that the bridge saddles on the E and G strings were completely maxed out until they wouldn't go down any further. I also noticed that the nut was filed down so much that the strings were resting on the fingerboard. I asked the salesman why the bass was setup like this, and if it was normal. He kept on insisting that everything was set to factory standards and optimum playablity, and that I should invest in getting it setup if I didn't like the way that it felt. I played it beforehand and it sounded/felt great, with the exception of the high string action which was due to an incredible amount of relief in the neck. When I got home I decided to give the truss rod a little tweak. When I was loosening the strings I noticed that the nut was cracked right on the D string(at that point I just tuned it back up and decided to leave the truss rod alone). It's my guess that it was setup with that amount of relief to compensate for the nut. Did I buy a defective bass(besides the cracked nut)? I don't know much about fretless basses, but I somehow feel that I purchased a lemon. Thanks in advance!
