Hey dude!
I know we've had a couple of comical too-and-fro's about my '73, but why exactly do you want an early 70's Jazz specifically? (or even a Reissue?)
Have you just tried broadening your search to any MIA Jazzes, bearing in mind that pretty much each bass can vary greatly.
Although I very much love my '73 and it gets played a lot, basically it's not going anywhere just yet, my 2003 MIA standard beats it to the number one spot. I've never ever played a bass that has bettered it for sound and feel, including Laklands, US Sadowskys, warwicks.....whatever!. All the '73 needs is a bit more TLC in the way of a refret and some new pickups to get it up there no-doubt, but my point is that my '03 is a completely stock, out the box MIA and blows everything I've ever tried out the water.
