These were originally made for the Japanese market. They're super rare outside of Japan. Actually got mine direct from Japan.
The Yamaha BB-VI is definitely in league with Fender Precision basses of the 1970's and 80's.
Many top players like Louis Johnson, Paul McCartney, Michael Anthony, and many others chose to play MIJ Yamaha's in the 80's.
Top two frets are in pretty rough shape. That's really the only complaint. Pino licks are at home on this all day!
