I don't care what features came in what decade - absolutely could NOT care less. All I care about is what I like to see in a bass. IMO Fender is under no obligation to reproduce any "era". Further, they specifically state: "...it boasts design touches from several periods in Jazz Bass history...". They're absolutely clear about that. Tuners not agreeing with the decal??? Pickups not agreeing with the neck? Oh please, give me a break - the bass is correct for what it is - the 50th anniversary model.
Here's what I see and what I care about:
Color-matching headstock? Check!
Inlays? Check!
Bridge and pickup covers? Check!
Tugbar? Check!
As far as I'm concerned, it's not confused, it's lovely! All it needs is binding on the neck and every one of my likes would be covered.
(As usual, opinion always available on request.)
Of course, Fender can do whatever they want, but if they're calling it a 50th Anniversary Jazz Bass, logic dictates that it should have some features of an original '60 J-Bass. Block inlays, (mid '66-'82-ish) binding, (Dec.'65-ish-'82-ish) thumbrest on top. ('74/'75-'82-ish) The chrome covers are common to all Jazz Basses form '60 through about '82, so that hardly counts. The matching headstock's cool and definitely vintage-like, but in fact custom color JBs before mid '62 (about the same time round lam 'boards appear) or so usually don't have one. So where's the beef? Nothing representaive of a '60 Jazz Bass. I have no problem with the bass itself, only what it's being represented as. Call it a "vintage amalgam Jazz Bass", whatever, but the 50th Ann. moniker is misleading and could've been applied to a bass closer to what the name implies.
For whatever it's worth, I started out (bought my first one in new '75) as a P-Bass guy, but after a year got my 1st Jazz and never really went back. Lover everthing about them, the shape, the narrow neck, the sound. Had a lot of gorgeous Pre-CBS Precisions over the years, (which I stupidly didn't keep) but for me, the J-Bass is the s**t. I need 2 pickups, kinda lost without 2.
I can always tell a Precision, Rickenbacker, or Gibson EB on record, Jazzes are a little harder to pick out. Which is why they fit any style of music, I guess...a Jazz is like club soda, it goes with everything!
As Greg Lake said in Guitar Player back in '74, the Fender Jazz Bass is one of the best basses in existence. (And he was playing a Gibson Ripper at the time he said that!) Still pretty true today...
