Street cred, yes....formerly known as "snob appeal". No doubt about it. Which, as you've pointed out also applies to expensive guitars.
Performance criteria aside, basses priced at the Fodera/Alembic/Ritter level deliver a different "flavor" of snob appeal, but snob appeal nonetheless. So if we're being totally honest, it's hard to deny that for basses at the very highest pricing tiers, the Snob-Appeal-o-Meter is pretty much "pegged".
Nothing wrong with snob appeal, or paying extra for the cool factor, or extreme craftsmanship for that matter. For myself, if my resources were unlimited I might never buy a Ritter bass, but I'd have a warehouse full of cars and bikes, new and old. It's all about personal priorities, and it's all good in my book. Cheers.
"Steet Cred" and "snob appeal" are two different things, but they can overlap. It also depends on whom one is trying to get street cred or snob appeal from.
If you play a gig with a beat up old Fender, you've likely got street cred from the musicians and the crowd. You're only getting snob appeal (yes, a pre-CBS certainly has snob appeal given the current prices) from those that know what it is worth. If you play the gig with a Fodera, the musicians *might* know what it is (likely not), and the crowd certainly doesn't know. Zero street cred. The snob appeal is there with the same demographic - those that know what the bass cost.
The thing is, if one actually plays their instruments, then you can't "put performance criteria aside." That's kinda the main point of the instrument unless you're a collector. I'll stand by my assessment - the Fodera P will play objectively better than pretty much any old Fender out there (will take lower action if you want, more consistent note-to-note, etc). But "vibe" is real (perception is reality), so there is more to it than measuring the bass setup. That still doesn't mean it is better for an individual - as you said, depends on their priorities.
As for old being cool or good, I get that. For about 5 years I tracked/raced a '79 Porsche 911SC. Low horsepower (by today's standards), and not expensive to buy (about the price of a Fodera when I bought it in the early 00's). I could have bought a Subie WRX that would have been much faster at the track. But the driving experience is totally different between the two. The Subie (and any current performance car) was fast and largely drama-free until you pushed it to 10/10s (which was pretty damn fast). The 911 otoh, had no power steering, no ABS, had an air-cooled motor, and would head into trailing throttle oversteer at the drop of a hat, often catching drivers out as they spun around. It was like driving a time machine. And I loved that experience.
For some guys, playing an old Fender gives them a similar playing experience - it is like being in a time machine. Totally worth the investment to some. But just like a Kia will get you from point A to point B in a similar fashion to a Porsche, the experience will be different. Just depends what you want. As for today, the 911 is long gone (racing is expensive). Now instead my "experience" difference is between these two
