The Private Stock “Super Eagle” is the result of a very close collaboration between Paul Reed Smith and Grammy-winning musician John Mayer. Some of the more distinctive and personalized specifications Mayer and Smith decided on for this special run of instruments include a longer (for PRS) scale length of 25.375”, specially-wound 58/15 JM treble and bass pickups with a specially-wound Narrowfield JM pickup in the middle position (with three individual coil-tap mini-switches), a JCF Audio preamp with treble boost, as well as a hand-signed sticker in the f-hole of the guitar that was designed by Mayer’s friend David Smith (who also designed the cover art for Mayer’s 2012 Born and Raised album).
