I read a Jerry Cantrell interview (in a recent guitar world) he reckons that certain signiture tones or voice come from your flesh and blood(how you hold your guitar, how tight etc.)

Anyway, my question is...why the hell would you try so hard to sound like someone else?...after 30 years, you obviously seem to have found/created your own voice...is this not the aim of every guitarist?
you lucky sod.
