There are early fury necks (on the ones with the slanted super ferrite pup, a la t20), which are pretty wide, 1 11/16 to 1 3/4. These are not jazz necks at all. However, later furys, the ones that are basically p copies, have a 1.5" nut width like a jazz, but the ones I've played feel slightly deeper (not much deeper) than a jazz. Both of my peaveys (Early fury with super ferrite and later model foundation) both have some neck dive, but it is not unbearable.
