But that won't really appeal to the large majority of the guitar market. Ibanez got their start doing really good imitations of real guitars, becoming popular, and then getting deals with high profile guitar players. If you just sold a guitar "shell" and appealed to an online forum, you would lose money from the other 70% of the Chinese guitar purchasing world who are just looking for a cheap beater for learning how to play guitar on only to throw away a month later.
Also it's easier to wind cheap pickups and buy cheap electronics than to pay a guy for quality work with quality materials regarding the frets, nut, and saddles.
