I'm starting a Jazz build, and I'm trying to decide whether to go with a Mighty Mite neck (rosewood board) at $110 or an All Parts fat neck (rosewood board) at $299. I generally like fatter necks, but I'm not sure why the All Parts would be worth three times the cost of the MM. The body is a recently acquired Squier Standard Jazz in basswood. It's fairly light as bodies go, though I haven't weighed it. The AP fatty would, of course, make it more neck heavy, though I plan to go with Hipshot Ultralite tuners to help with that. FWIW, the rest of the build details are: DiMarzio Model J pickups, CTS pots (probably 500K this time), .047 Orange Drop, Schaller 3D roller bridge. The goal is to have a thumpy Jazz Bass that would negate the need for a P Bass. Aside from the fuller profile, are there benefits that would justify paying three times as much for the All Parts fat neck? (Advantages might include things like a thicker headstock or known compatibility with the Hipshot Ultralite tuner bushings.) As it stands, I'm inclined to go with the MM. (The MIM Fender Jazz neck, at $200, falls right in the middle of those price points but doesn't seem to offer any advantages other than the decal, which I don't need.) Thanks for any advice.
