Part of John Mayer’s goal with the Silver Sky was to bring a modern aesthetic to a classic design. As we developed the guitar, we were pulling materials and colors from modern references, and we both thought the gray buttons added unique, modern vibe to the guitar. In addition, they are incredibly lightweight, which supports the tone and resonance of the guitars. So, like with everything, it was a look, feel, and sound based decision.
