I don't know the whole story, but the general consensus is that when they (Yamaha) were seriously trying to take market share from Fender they were chasing serious endorsers. One of these was supposedly Jeff Berlin, who had been given a BB3000. He supposedly specified a 1.5" nut version with V/V/T which became the BB3000s. At the end of the day he never became a Yamaha endorser but the BB3000s was placed on the market anyhow. I've no idea why (or at least I've read dozens of theories and don't which is true) but initially the manufacture of these was subcontracted to alembic.
Incidentally, I don't know if you're aware but they still build the BB3000 in Japan, with a street price of about 190,000 yen, which isn't bad considering the strength of the pound against the yen. The BB3000s's sold even less than the BB3000's back in the day.
There's a heap of Yamaha basses that never saw the light of day outside of Japan which most people have never heard of (like the 2000VI) - if you manage to collate accurate data on all these that would be impressive!
