Yet another reason I don't patronize Warmoth. Very limiting "pre-canned" products is the first. You usually can't break out of certain, very important, options, like fretboard radius, or truss rod style, within a certain neck model. I can't tell you the number of times I have started spec'ing a Warmoth neck, only to scrap it because the 10" radius, or some other fairly typically spec'able feature that matters to me, is locked in. Secondly, they are not very open to custom requests IME. Thirdly, they don't have very many neck profiles. Finally, their fret work is incomplete...not to mention that a 30 end degree bevel and glued in frets aren't the ideal way to do things IMO. The only other big custom neck maker I have used who doesn't send their necks out of the shop with fully finished fret work is B. Hefner, who charges $120 extra (and he is also a real piece of work IME). Musikraft and Guitar Mill make necks with more "where the rubber meets the road" options, and do top notch fret work as a matter of course (especially Guitar Mill) for no extra charge. Haven't used USACG, so can't say. Warmoth didn't used to be this way, but they have become extremely robotic in recent decades. They are known for interesting wood options; that's "their thing." They also have about a billion inlays (most extremely cheesy) to choose from. And their quality is usually fine, fretwork aside. If that's what you want, that's a good place to go. But most other to-spec makers offer more in the ways of tweaking the important "beyond the cosmetic" options to your personal preferences.
