The Silver Sky came out of a close collaboration between John Mayer and Paul Reed Smith, built from their favourite elements of 1963 and 1964 instruments. It's an alder body with three 635JM single coils, a bolt-on maple neck, 22 frets and a 25.5" scale.
A few specs set it apart. The 7.25" radius is rounder than the 10" used elsewhere in PRS's Bolt-On line, so the board curves more under your fretting hand. The steel tremolo uses Gen III knife-edge screws and is set flush to the body, which means it only moves down in pitch. PRS inverted its own headstock shape to keep the string length behind the nut consistent, and the vintage-style tuners lock.
This is for the player who loves a three-single-coil guitar of that era and wants one built to PRS's standard. If a humbucker at the bridge appeals, the Fiore is the comparison, and the Silver Sky Satin is this model in satin nitro. Our pick is Polar Blue, the colour we picture first when someone says Silver Sky.
The Fingerboard option is rosewood or maple, and it changes the neck too. Maple comes with the original 635JM shape, while rosewood carries the 635JM-R, which PRS reshaped in the shoulders to feel more rounded. Both keep the 7.25" radius and Small Birds.
