The Martin OM-John Mayer, 20th Anniversary Edition is a celebration of the iconic artist's custom guitar. Styled in a sleek Gray Sunburst finish and bearing a unique label with John Mayer and Chris Martin's signatures, this gorgeous 000-14 size acoustic is truly one-of-a-kind. Crafted from Engelmann spruce and East Indian rosewood, you can expect warm, articulate tones with a sweet top-end and ample low end. Its low-end is backed up by Martin's scalloped X-bracing pattern, giving the OM-28JM plenty of scope for powerful chords and driving rhythms - and thanks to its versatile orchestra body shape, you can switch between intricate fingerpicking and flowing strums to suit virtually any style and genre. Speaking of playing styles, a standard taper neck profile and a select ebony fingerboard allow for smooth navigation of the 20 finely finished frets. Topping off this incredible signature is a set of Fishman Gold Plus Natural electronics, which provide a stunningly lifelike reproduction of the OM-28's character.
