My S-Type guitars are based on the Fender Stratocaster neck and body shapes. I buy the bodies, made to your specifications, from two places nUSA Custom Guitars and Warmoth Guitars. To see what you will generally have as options, check their websites by clicking on their respective names above. Generally speaking, USA Custom Guitars will be more receptive to special design requests and options, like neck profiles beyond 3 basic ones or body shapes not on their website, and often without an upgcharge. These are avaiable in a variety of forms:vintage, American style, lam or drop top, hollow, semi hollow, F-holes, and so forth.
