The new satin nitro Moc Sand is an amazing finish, it feels great! The frets are also a hair taller on 2021 models. And they both sound great clean or with any amount of drive. For what used Fender John Mayer’s are listed at, it’s worth it to take a Silver Sky for a spin. I don’t even care about it being a John Mayer model - it’s just spec’d exactly right for me, and they play nice with my other strats as well.
