John Mayer’s Fender Custom Shop Jeff Beck Stratocaster ‘Heartbreak Warfare’
John was first seen using this guitar following the release of fourth studio album ‘Battle Studies’ in 2009. The guitar was used exclusively for the song ‘Heartbreak Warfare’” which features quite extensive use of the tremolo.
The main distinctive features on this guitar are the 24-fret neck with what looks like a Wilkinson split roller nut, and three Fender Noiseless pickups. Based on this, the guitar appears to be a Jeff Beck Signature model – since all of those features are present on that model, although John’s guitar doesn’t seem to feature the usual Jeff Beck signature on the headstock (it is possible that the signature is simply on the back instead on the front).
