Most guys know what equipment their favorite guitar players used. It's pretty common knowledge what Angus, EVH, Gilmour, Page, Clapton, or Hendrix used. There may be a new generation of guitarists that will use devices like the Kemper, or Axe for their tone and it may not be something that is conventional at all. If it's the Kemper, they might profile an obscure amp or even a common one that is heavily modded, never upload the profile and that could be their tone. In interviews they could just say they use a Kemper and no one will ever know the specific amp, making it difficult to get close to their tone right off the bat. Could be the same with the Axe II. They could use a certain model pre, with a different model power amp and tone chasers everywhere would be scrambling to duplicate the tone. One the other hand, have we become so traditional that all "great" tones are just minor variations anymore and there really aren't any new great tones to be discovered?
