Part of Martin’s re-imagined Standard Series, the J-40 sports vintage-inspired touches like antique white binding, aging toner on the Sitka spruce top, and gold open gear tuners with butterbean knobs. It also has a Modified Low Oval neck with High Performance taper. The classic tight-waisted jumbo body shape still features East Indian rosewood back and sides and a hand-fit dovetail neck joint. It produces a tone that is beautifully balanced with powerful response and projection.
