Wow. I can see I'm going to have to help you fellas out.
The Yamaha Blue Jeans bass, including the one from the link Invalid Link Removed is a bass yamaha made in the 60's, from what I can tell. The one in this ad is a 1966, selling for the equivalent of 1,436.57 USD
The instruments currently being made by Yamaha are:
the SBV-500: [Invalid or Expired Link Removed]
the SBV-550: [Invalid or Expired Link Removed]
and the SBV 800MF: [Invalid or Expired Link Removed]
Priced at the equivalent of 384.79 USD, 410.44 USD and 684.08 USD, respectively.
I understand a lot of guys order from Ishibashi to have the instruments sent to the US, here are the links for these basses:
[Invalid or Expired Link Removed]
(price 307.83 USD)
[Invalid or Expired Link Removed]
(price 344.77 USD)
I could only find in-Japan shops selling the SBV-800MF, but could look some more, if someone was specifically interested.
I'm basically an acoustic bassist, and don't visit the electric side of the board often, but don't mind to help with these kind of things, if you PM me.
