When your musical cravings call for big, booming sound, what better acoustic to fit the bill than the Eastman AC630 jumbo? Boasting a handcrafted, solid wood construction and Eastman’s superior build quality, the AC630 is ready to dole out tones powered with magnificent projection. The majestic voice of this jumbo builds upon the rich tones of its European spruce top and gorgeous flamed maple back and sides. Then, Eastman craftsmanship swoops in to offer a top-notch playing experience, courtesy of a Traditional Even “C” maple neck, hand-scalloped X-bracing, a dovetail neck joint, and dual-acting truss rod. Sweetwater highly recommends this bold-voiced guitar to any musician looking for tone that will make a splash on any stage or in any studio.





A bold, booming voice with good looks to boot





Eastman sets guitarists up for a superb playing experience, boisterous tone, and powerful projection with the AC630 jumbo acoustic guitar. By selecting a tonewood duo of European spruce and flamed maple, they concocted an acoustic voice that rings clear and resonates deeply. And with a body width spanning 17 inches, the tonewood choice is key in clearly translating this guitar’s qualities and cohesive voice. The flamed maple gives this guitar an undeniably beautiful appearance, making it a great companion for gigs. Meanwhile, the maple neck and silky ebony fingerboard contribute to player comfort, featuring a Traditional Even “C” neck carve and a 12-inch fingerboard radius.

Functional build and stunning looks





Beneath the hood, a combination of dovetail neck joint and Hand-scalloped X-bracing reveal the secrets to this guitar’s enhanced resonance and vibrational transfer and result in a projective voice devoid of inconsistent frequencies. Eastman then applied Truetone gloss to the AC630 jumbo, a finish marking the perfect middle ground between hard and flexible to let the resonance project uncompromisingly. Lastly, a bevy of intricate pearl and abalone inlays finish this jumbo acoustic off with gorgeous looks to match the sounds inside.
