The E40OM Thermo-cured Traditional acoustic guitar by Eastman Guitars pays a timely tribute to the orchestra model body shape that made an indelible mark on music history. The E40OM’s quintessential features begin with the tapered waist of a 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 OM ? minus the sticker shock. And the E40OM is beyond hospitable to players. Its 24.9-inch scale, ebony fingerboard, and “C”-shaped mahogany neck fuel friction-free playability that’s easy on hands and fingers. Moreover, a bevy of detailed handiwork provides old-school elegance that’s candy for the eyes. The double-bound body boasts striking iridescent trim work and an abalone rosette that perfectly frame a Truetone gloss finish. Tap into a historic dreadnought sound and see what the buzz is about with the E40OM Thermo-cured Traditional acoustic guitar from Sweetwater!





Handcrafted for mature, seasoned tone





The E40OM Thermo-cured Traditional acoustic guitar emphasizes spruce and rosewood tonewoods and the resulting sound teems with refined 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 E40OM’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 E40OM’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 E40OM’s detailed appointments are crafted using high-quality materials such as hardwood ebony. The bridge pins, bridge, and saddle are all made from ebony, and the bridge adds inlays made of abalone shell. Once paired with the E40OM’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/abalone 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!
