I'll change the strings. I reckon it must be the Pure Blues - lower tension. I'm actually gonna throw some flats on it, and will take it from there. Thanks, guys, and Grangur - thank you for the in-depth tutorial - I'll run that test and take it from there.

You don't have to try flats JUST because of the clak! (unless you were already pre-disposed to flats ). Just follow grangurs advice (although I would use an actual measuring tool personally).
It will take 10 mins - and will give resounding information for the future. I'd measure you favourite bass (i.e. your favourite setup on your basses) and try to more or less copy that on the Jazz. The tension of the strings is a factor in clak, but nowhere near as much as neck relief and string height, as well as playing style of course.
...and yeah, setup 'from the factory' is almost completely null and void by now, even if (big IF) it was done remotely well.
