When you're ready to command the room with uncompromising tone and bold visual presence, the Martin J-40 delivers — available now at Haggerty’s Music. Originally introduced in the 1980s, the J-40 was Martin’s answer to players seeking the power and projection of a Jumbo body with the elegance and craftsmanship of a high-end Standard Series model. Designed to blend the depth and resonance of classic dreadnoughts with the balance and nuance of smaller-bodied instruments, the J-40 quickly earned its place as a versatile, premium choice for solo performers and recording artists alike. Its tight waist and wide lower bout give it a unique voice — rich in overtones, full in the low end, and crisp in the trebles — making it a standout for any genre, from fingerstyle to folk to full-band acoustic sets.

Now reimagined for 2025, the J-40 carries forward its legacy with modern refinements that enhance tone, comfort, and stage presence. It features solid East Indian rosewood back and sides paired with a solid spruce top finished in a vintage-style Aging Toner. Forward-shifted GE scalloped bracing, borrowed from Martin’s Modern Deluxe series, provides improved responsiveness and sustain, while the genuine mahogany neck sports a GE Modified Low Oval profile with a high-performance taper for effortless playability across the fingerboard. Abalone hexagon inlays, multi-stripe purfling, antique white binding, and gold open-gear tuners provide the kind of tasteful detail that defines Martin’s top-tier craftsmanship. Whether you're writing, recording, or performing, the J-40 is a guitar that tells your story — boldly, beautifully, and without compromise. A hardshell case is included for dependable protection.
