if you try out a fender jazz bass neck in a store and like the sound pay attention what the neck and body are made of this will give you the perfect tool for building one, I have a 2008 usa made jazz bass the neck twisted 3 months ago and went to warmoth to get a replacement neck all maple ,slim taper, tush nut, stell rods inside neck. wow it sounds way better than any fender I have ever heard. the steel rods add sustain and it has no dead spots, fender doesn't have the quality of wood like warmoth. usa made fenders are pieced together in corona california and mexico. fender hasn't made any intrument in the usa in awhile it's all a lie. buy a warmoth and you will hear the differnence
