So after some more research I figured out why that Aerodyne neck feels so comfortable and familiar to me compared to other Jazz basses I've played. While it has the normal 1.5" Jazz bass width at the nut, the radius on the fingerboard is like that of a P-Bass (7.25" as opposed to the 9.25" of normal Jazz basses and vintage Fender guitars) so it feels more rounded while being thinner. This is also the reason I don't care for Spectors and Warwicks. Spector's fingerboard radius is a wicked flat 16" and Warwicks are about the same.
I wash born here, an I wash raished here, and dad gum it, I am gonna die here, an no sidewindin' bushwackin', hornswagglin' cracker croaker is gonna rouin me bishen cutter.
