    Hi everyone,

    I know that in the 60s, the Jazz had a round radius and at some point in the 70s, they moved to a flatter radius. Does anybody know when that transition occurred?

    AFAIK the 70's instruments still had the 7.25" radius unless there's something I've never seen. they did start using larger fret wire in the mid-late 60's but that's the only changes that i'm aware of besides some changes in the rear of the neck profiles.

    They were all 7.25" radius (as far as I know, ALL the instruments made in the US, 'though it's possible the short-lived Archtops like the LTD and perhaps the flat-top acoustics) until they introduced the Standard and Elites in '82.

    I had one early 60s jazz and have had several 70s era. The 60s era jazz had a very different neck profile. The 60s had a very thick neck front to back and the back was very rounded (a deep C). My 70s era jazz basses had more of a shallow D profile. Thinner front to back.

    Maybe because of the vastly different neck profiles, I thought the radiuses were different too.

    Radius is used to describe the curve on the fretboard itself which is 7.25" for all 60s and 70s Fenders, neck profile is a totally different thing and did vary...
