Martin Standard Series J-40 Jumbo Acoustic Guitar, Rosewood Back & Sides, Spruce Aging Toner

Manufacturer's Description

The Martin J-40 is a trusted standout in Martin’s acoustic lineup that makes an unforgettable statement in both sound and style. Its Jumbo body size combines a larger, tight-waisted shape with powerful projection, delivering resonant bass, shimmering trebles, and exceptional balance that suits any playing style. Handcrafted with a solid spruce top and solid East Indian rosewood back and sides, the J-40 boasts deep bass and rich overtones, creating a sound that’s as dynamic as its design. The satin genuine mahogany neck with a Golden Era (GE) Modified Low Oval profile, high-performance taper, and 25.4" scale length ensures smooth, comfortable playability. Luxurious details, including its abalone rosette and bound ebony fingerboard with hexagon inlays, enhance its timeless beauty. Complete with antique white binding, an ebony bridge with bone pins, and gold open gear tuners, the J-40 is a guitar you can trust to unleash the artist within. 

Martin’s refreshed Standard Series for 2025 enhances tone, comfort, and style. Sitka spruce GE top bracing, as featured on the Modern Deluxe Series, delivers vintage-inspired tone and sustain, while updates like a reimagined neck profile, thinner fingerboard, and refined bridge and heel improve playability and aesthetics. Each guitar includes a hardshell case.
