I've got a non fender jazz bass body made of ash, loaded with EMG's, with a BA II bridge. This bass has been my main player for a long time. I had an Ibanez Black Eagle Neck on it. I finally found a Black Eagle bass body so now I need a neck for my main player. I want to use an original equiptment jazz neck this time. But which...American or Mexican. What is the main difference between them. The only visible difference I can see from pictures is the American jazz has the star truss rod adjuster at the base of the neck and the Mexican neck has it up by the headstock. I prefer it at the headstock because it seems easier to deal with, but this is not the deciding factor. This place called STRATosphere sells 2008 replacement Fender necks on e-bay, both American and Mexican. Has anyone had any experience with them?
