People who spend lots of bucks on vintage guitars are usualy collectors and not realy looking for tone or stuff ... Can't blame them , others pay millions for some old painting or an antique.

If someone looking for tone & can afford $15,000 for one guitar , then he can probably have a couple of guitars customly made of best woods to his own specifications that would sound like nothing else , and perhaps a custom amp too (not sure if that's a great idea) !

My 2 cents.
