One of our best selling guitars here at Rudy’s, the OMJM model is a perfect signature model, in our opinion. It is a great mix for John Mayer fans and Martin fans, with a, elegant Engelmann spruce top with East Indian rosewood back and sides. Electronics make it instantly stage ready. A long scale length and 1 11/16" nut width make it feel easy to play and easy to dig into. Also includes a deluxe Geib hardcase. "In light of his ever-expanding reputation and fan base, Martin collaborated with John Mayer on the creation of a second namesake guitar, one with many of the same attributes as his first OM-28JM Limited Edition, but one that would be more affordable and more widely available in the tradition of the popular Martin 000-28EC Eric Clapton model. This tasteful Orchestra Model exhibits versatility for today's diverse contemporary musical styles."
