Shuker J bass custom

[Bassy]

Hi, does anyone have a Shuker J bass with the custom shape? It's shape is designed with deeper cutaways to work with a 24 fret neck. I was wondering how different the body shape is from a standard jazz?

Longer top horn, but slimmer body?

Jon has the bodies shown on his site, but I've seen a few variations - attached pics of basses with slightly wider bodies, curved top horn...or am I imagining this?

Also is the body very small? P bass size?
