John Mayer debuts a new prototype Silver Sky that has been fitted with an Alembic Blaster

Are we about to see an evolutionary leap in the design of John Mayer’s much talked about PRS signature guitar, the Silver Sky? Mayer has been spotted onstage with Dead & Company playing a prototype Silver Sky that augments the controversial but brilliant S-style with a host of new specs.

It is not unusual to see Mayer using a prototype, and that said prototype has offered a trailer of electric guitars to come, but this is more than simply a variation on a theme and a fresh lick of paint to get the internet talking.
