it is 60s, but you also have to know that back then Fender quality control, wood, how were they build was actually stinky poo and by that every JB that I've tried throughout my years of playing were not that great instruments.
I found my '66 that I really like (personal taste), so I also have Moollon B524, and it's great same vintage vibe 5 string, but comparing bass next to one and another is whole different approach. You can have two jazz basses from same era, and they would feel different and sound different. My choice was mine '66, I had option of getting for almost the same money the '65 JB, but this one was just better. So preCBS, CBS, Japan, there are good and bad instruments, but for Moollon I know for fact they build them so every bass is great. That's why I would like to compare it with my JB
But, thank you for your experience and post!
