Classic style with a hint of 2018, Martin introduces the J-40 jumbo-style acoustic guitar. With its 2018 features complementing the classic construction on this beauty, you can expect to get a gorgeous, big sound that projects. The Martin 40 Style appointments give this guitar its unmistakable premium aesthetic. For guitarists who have searched time and time again for the perfect powerful sounding acoustic, the J-40 is the one for you.

2018 Features
In 2018, we're introduced to an array of updates, including a modified low oval neck with Martin's High Performance taper, which gives you the unparalleled comfort and playability. The Sitka spruce scalloped forward shifted "X" bracing provides you with the superior projection and sonic horsepower, especially when paired with the Jumbo-sized body and rosewood. The top wears an aging toner gloss finish while the headstock comes fitted with gold open-geared tuners with butterbean knobs, giving it a classy, vintage look.

Classic Construction
The Martin J-40 has a tight-waisted East Indian rosewood jumbo body topped with a Sitka spruce top. The fingerboard is made of ebony and of course with these tonewoods, you get the incredibly deep, rich sound that Martin guitars are famous for. Sonically, this traditional Jumbo construction and fantastic pairing of tonewoods make this J-40 the perfect choice for strummers looking for outstanding volume, projection, and punch.

Martin Style 40: Reimagined
Just like all Martin instruments, the Style 40 Martin guitars are all about premium quality, tone, and craftsmanship. What really sets the Style 40 guitars apart from the rest of the Standard Series are the absolutely breathtaking aesthetics and upscale style they offer. Future heirlooms that are sure to please discerning players for years to come, the Style 40 Martin guitars are made using the finest East Indian rosewood and a Sitka spruce top with hand-carved scalloped bracing for a deep, rich, powerful voice that's delivered with exceptional clarity. The updated forward shifted bracing on most models (except OM-42 and 000-42) will add some extra sonic horsepower to your sound, especially on the low end. Each model also sports Martin's ergonomic High Performance neck taper to provide you with superb comfort and playability while a selection of gorgeous abalone pearl adornments cater to its exquisite looks. Aging top toner, Antique White binding, and gold open-gear tuners give the Style 40 guitars that unmistakable old-school Martin vibe.
