Yamaha SB5A, sunburst, made in Japan 1967. The 'Flying Samurai' was a Yamaha original shape that debuted in 1967; they were made for five or so years before disappearing into obscurity for several decades. The bass in the line came in two versions, this one was the higher-end version with two pickups instead of one. It's a medium scale with a moderately slim neck, and the odd body shape balances remarkably well...  it feels great. The pickups are good quality and produce a thumpy, round tone with nice but of snarl on the top. The neck pickup is full and fat, while the bridge adds aggressive mids and plenty of bite. The frets and finish are in excellent shape for an instrument this old, it's quite remarkable. The shape is truly fantastic, and with all the quirky hardware and that classic burst finish, this looks like a million bucks. I'm a big sucker for these, because heck: it rules.
