John Mayer’s 1959/60 Gibson Les Paul Junior
John was seen using this guitar on a few occasions in 2007, including the ABC-TV’s “Good Morning America” on July 20th, 2007. Unfortunately, the specifics and the origin of the guitar are currently unknown.
Based on the photos, the guitar appears to be vintage, most likely dating back to the late 50s. It features a double cutout body, cherry red finish, and a single P-90 pickup in the bridge position.
