From Fender:

"The Fender® American Vintage II series presents a remarkably accurate take on the revolutionary designs that altered the course of musical history. Built with period-accurate bodies, necks and hardware, premium finishes and meticulously voiced, year-specific pickups, each instrument captures the essence of authentic Fender craftsmanship and tone.

When Don Randall at Fender Sales requested a more sophisticated, high-end bass model, the now iconic Jazz Bass® was the result. The neck was narrower at the nut, providing a faster and more effortless feel and the sleek new body style mirrored the offset contoured style of the Jazzmaster®. By 1966, evolution of the instrument reached new heights with striking new features.

The American Vintage II 1966 Jazz Bass features a comfortable “U” shape hard rock maple neck, and it plays like a dream with a 7.25” radius round-lam rosewood fingerboard and vintage tall frets. Characteristic of production in 1966, this J-Bass® is offered with white neck binding, pearl dots, two volume controls with master tone, matching painted headstock and 4-ply tortoiseshell pickguard. The 4-saddle bridge with threaded saddles, vintage-style “lollipop” tuners and Pure Vintage ‘66 Jazz Bass pickups deliver classic thump and style.

The instruments in the American Vintage II series are direct descendants of the original Fenders: designed for players with a fine appreciation for vintage Fender tone and feel and built with unmatched quality, down to the last screw. These are Fender electrics in their purest form: Fender American Vintage II, the stuff of legends."
