John Mayer has been busy since he introduced the Martin 00-45SC John Mayer Stagecoach Edition – his imagined “stagecoach cowboy guitar,” bedecked with gorgeous blue Paua pearl inlay throughout – at the National Association Of Music Merchants Show in January 2012. The seven-time Grammy Award-winner put the finishing touches on Born and Raised, his fifth album. Released in May, Born and Raised became Mayer’s third album to reach No. 1 on the Billboard “Top 200” list, a position it held for two weeks. The album also garnered rave reviews and produced two singles: “Shadow Days” and “Queen of California.” Plans for a North American concert tour were derailed by a recurrence of vocal problems that silenced Mayer early in the decade, but while receiving treatment and resting his voice, he played guitar for vocalist Frank Ocean on “Saturday Night Live,” at the “Love for Levon” concert honoring the late Levon Helm and on tracks for legendary pianist Chuck Leavell’s next album. As for the Martin 00-45SC John Mayer Stagecoach Edition, the very limited edition of 25 guitars sold out almost instantly.
