John Mayer's personal Arles Blue Land Rover Defender inspired this limited-edition finish, one of just four heritage colours drawn from the iconic British 4x4. PRS and Mayer have turned the Silver Sky into a tribute to automotive design, complete with a painted headstock and a serialised neck plate marking this as 1 of 500 guitars in Arles Blue. The Defender Color Collection spans 2,000 instruments globally across four finishes, each shipped in a custom ATA moulded case bearing a "DEFENDER" badge. This is the Silver Sky platform refined through PRS Core-series execution, now wearing colours that matter personally to Mayer rather than generic vintage palettes. The Silver Sky maintains its bolt-on maple neck, alder body, and trio of proprietary 635JM single-coil pickups developed to capture the response and clarity of the reference instruments Mayer and PRS studied. Fingerboard radius sits at 7.25 inches with 22 frets, and the tremolo system uses a two-point knife-edge design with vintage-style bent steel saddles. PRS has applied the Arles Blue finish to both body and headstock face, a detail typically reserved for Private Stock and select limited runs. Tuners are locking, nut material is synthetic bone, and the five-way switching offers the expected single-coil combinations plus a neck-bridge option in position four. The matching painted headstock distinguishes this from standard production Silver Sky models, which ship with natural maple. Each neck plate is laser-engraved with "Arles Blue" and its production number out of 500, providing verifiable provenance for a run that won't be repeated. The included ATA case features custom badging and compartmentalised foam specific to the Silver Sky body shape, designed for flight transport and tour-grade protection. Mayer's Defender sits in his personal collection; this guitar translates that automotive palette into a Core-spec instrument with the playability and output the Silver Sky platform established in 2018.
