I currently play a 1996 Made in Japan Fender Jazz '75 Reissue. The neck is slim and "shallow" for lack of a better term. The reason I say "shallow" is that I used to have a Aerodyne bass with a "C" shape neck and 7.25" radius neck and it felt thick or "chunky" to me compared to the '75 reissue. I can only guess that they have different radius'. I'm looking for additional basses with the same neck "thickness" as my beloved '75 Reissue but don't know what to look for. Does anyone know what the radius is on a '75 Reissue and is it indeed the radius that determines the "thickness" of the neck?
