Part of Martin’s refreshed Standard Series for 2025, with enhanced tone, comfort, and style. The Martin J-40 is a standout in Martin’s acoustic lineup, offering a bold statement in both sound and design.

Its Jumbo body size features a larger, tight-waisted shape that delivers powerful projection, resonant bass, shimmering trebles, and exceptional balance, suiting any playing style. Handcrafted with a solid spruce top and solid East Indian rosewood back and sides, the J-40 produces deep bass and rich overtones, offering a dynamic and full-bodied sound.

The satin genuine mahogany neck features a Golden Era (GE) Modified Low Oval profile, high-performance taper, and 25.4" scale length for smooth and comfortable playability. Elegant details include an abalone rosette, a bound ebony fingerboard with hexagon inlays, antique white binding, an ebony bridge with bone pins, and gold open gear tuners. Comes with a hard shell case.
