Re: Fender P-bass necks: MIJ '57 reissue vs. MIM Classic 50s

The '57 re-issue necks are wide but relatively slim front to back. Not
what I would define as "chunky" like I would a '51 re-issue.

Exactly. I've owned a '57 RI (made in USA) and the neck was pretty wide but
thin and flat. Not chunky at all.
