The balanced sound produced by the E22 "OO" acoustic guitar's emphasis on walnut and spruce tonewoods enables studio professionals and singer/songwriters to blend the E22 with other instruments and vocals in real time. Essential components include solid walnut sides and back. In addition to bringing a clean, crystalline presence to highs, walnut's robust middle highlights crucial tones for unwavering intelligibility, which organically improves your sound with openness and width. Additionally, Eastman selected Adirondack spruce for the top of this E22. Bright, woodsy clarity is provided by the solid walnut back and sides, which are double-bound for appealing durability. The traditional even "C" is carved on a mahogany neck. Its 24.75-inch scale length and ebony fingerboard provide the strings a smooth, expressive feel.
