New jaco fretless setup advice

[Tim1]

I have a new Fender Jaco Artist fretless due to arrive in the next few days. I normally tweak the neck relief and file the nut to suit if necessary when I acquire a bass, and am competent in doing this. However, I have no experience with a fretless and am seeking some basic advice please. I have done the research and the consensus seems to be that neck relief should be flat. Is there a figure for string clearance at the nut that I can use to set it? I understand about "mwah" versus fret buzz etc. but am very wary of cutting the slot too low - with frets as a guideline it is a simple job, fretless I am far less sure. I do have the correct nut files etc.
Mind you, the bass may arrive with a perfect setup that suits me - not my normal experience though. Any thoughts/advice much appreciated guy, and in case you had not noticed I am in New Zealand and had to order the bass in sight unseen although this has never been a problem for me in the past with Fender gear.

With a bass that expensive and at the same time collectible, I have to suggest just getting used to the setup. Check the intonation. If it's right, maybe leave it be.

The nut slots should be as low as possible without the strings actually touching the fingerboard. The thickness a business card (not credit card) is more than enough. I like lots of "mwah" but my fretless needs a little relief for my playing, certainly less than 10 thousandths.

Sorry bro, wrong. Optimizing an instrument to play right never decreases it's collectible value, even if it's a 1959 P bass etc. Optimizing the nut is no different than tweaking a truss rod in that regard.

I scored a Japanese version, a Bacchus BJB JP, secondhand. Flew it into Australia and it was perfect out of the box. After some acclimatization however, over a couple of months, the mwah all but disappeared. Still, all I had to do was adjust each string's height at the bridge, only slightly, and everything was tickety boo once again. Haven't had a hint of a problem since. I imagine you're in for a very similar experience. And I guarantee you're gonna have some FUN!
