John Mayer’s Novax Expression
This guitar was featured on the cover of John’s 2001 album ‘Room for Squares’. In the DVD commentary of ‘Any Given Thursday‘ he states that the guitar was used live for ‘Neon’, and in the studio on the song ‘Room for Squares’.
As you may have noticed, the guitar features angled or fanned frets, which allows for better intonation when compared to a standard guitar. The principle on which this works is based on making the lower pitch strings shorter by making the bridge and the nut angled, and on the opposite side making the bass strings longer.
