The E40D Thermo-cured Traditional acoustic guitar pays a timely tribute to Western dreadnoughts that made an indelible mark on music history. The E40D’s quintessential dreadnought features begin with a powerful, loud sound chamber framed by solid rosewood back and sides. Next comes a spruce top that’s thermo-cured for mature, seasoned tone. The result is an acoustic guitar that feels, sounds, and looks like a vintage dreadnought ? minus the sticker shock. And the E40D is beyond hospitable to players. Its 25.4-inch scale, ebony fingerboard, and “C”-shaped mahogany neck help players tackle countless styles and a variety of techniques. Moreover, a bevy of detailed handiwork provides old-school elegance that’s candy for the eyes. The double-bound body boasts tortoiseshell trim work that perfectly frames a Truetone gloss finish. Tap into a historic dreadnought sound and see what the buzz is about with the E40D Thermo-cured Traditional acoustic guitar from Sweetwater!





Handcrafted for mature, seasoned tone





The E40D Thermo-cured Traditional acoustic guitar emphasizes spruce and rosewood tonewoods and the resulting sound teems with powerful projection and chiseled note-by-note definition. Rosewood back and sides fuel a strong emphasis on fundamentals, thus ensuring the bell-like resonance that flatpickers and fingerstylists love. What’s more, the E40D’s Sitka spruce top is hardly an ordinary cut of wood. In its natural state, Sitka provides outstanding projection and a quick dynamic response, and the E40D’s top takes these traits to an innovative extreme via thermal curing, a low-heat process that speeds up natural aging. Thermal curing draws out organic compounds such as water and plant sugars. By extracting those compounds at the point of manufacturer, the wood is rendered lightweight and flexible with a heightened capacity to carry vibrations. Lastly, scalloped spruce X-bracing coerces rosewood and spruce into a sonorous, balanced union that’s ready for any style of music.





Abundant handiwork, professional appeal





The E40D’s detailed appointments are crafted using high-quality materials such as hardwood ebony. The bridge pins, bridge, and saddle are all made from ebony. Once paired with the E40D’s bone nut and saddle, ebony hardware facilitates mature, unrestricted resonance that plastic components simply cannot match. Moreover, the headstock features rosewood detailing and a pearl logo. The finishing touch is a Truetone finish by Eastman, which seals your guitar’s beauty under a thin, durable, and protective layer without dampening resonance. It’s safe to say we’re impressed ? now, it’s your turn!
