First off, - that's a great example of a beautiful bass. I remember the catalogs from then - great stuff to look at for sure.
Bass Bridges - IMO - I've been playing 50+ years and went thru a lifetime of mods. I've had basses with every new version bridge (including The Brass Age, BAI, BAII, Gotoh, Hipshot eg etc) as it came out.
Bass Bridges remind me of mousetraps - every design level of basic/complexity has been and is addressed enough (so far). Enough to warrant a museum devoted to their design. Personally, if you can't find a bridge to suit you at this point, design it yourself or hammer in some nails.
Personal favorites: love the Schaller 463 Roller Bridge; I do like Babicz full contact.
Best Overall - Fender '62 Threaded Saddle Bass Bridge Allows for string to string spacing, you can adjust everything with a screwdriver. I put these on several builds.
I understand the fascination with complex designs. It's the engine that keeps all the "sharks"* swimming forever.
* - keep re-inventing something that's already as efficient as it gets. Sharks (and alligators/crocodiles) have not changed for millions of years.
We can make it different but you won't make it much better!!!!
Love that bass. Great catch!
