Mine also had a 3 bolt neck, but I don't think it had the 70's bridge pickup spacing.
I saw one around the same age (2008) with a white body and matching headstock, which looked fabulous contrasting with rosewood, blocks and binding.
If I'd won the lottery last night, I'd fly to Tokyo and try a few out to see which one spoke to me.
I considered importing one but, buying one blind, I'd be concerned it might end up being another perfectly good instrument that I just didn't 'bond' with.
But if you decide to move this one on, I'd certainly like to give it an audition. 😉
I think I'm probably quite local to you these days.
Great looking bass.
