John Mayer posted footage of himself – from the neck down – performing a guitar cover of the Justin Timberlake ‘FutureSex/LoveSounds’ track ‘I Think She Knows Interlude’ (from ‘LoveStoned’) on Sunday (January 13). Mayer wrote, “Heard this in the car today, wanted to try it out… Collings I-35 through a Roland Space Echo pedal, Cornish NG-2 Fuzz and Fender ’64 Vibroverb… Looped through a Boomerang pedal.” Watch it via YouTube below.
