Cline is an incredible player, no doubt about that. And his JM is arguably the most famous one out there. It would just look like a black/tort heavy relic but having the fake Mastery bridge does make it look like an obvious take on his guitar. That being said, Fender produces MIM maple strats in Gilmour colors and rosewood burst Mayer looking ones, this is not nearly a first. Cline has never been a Fender endorser so I'm not sure what they are supposed to owe him.
