From Martin:

"Modern playability and classic looks—the all-new SC-18E pairs technology with timeless style and tone, combining SC innovation and Standard Series appointments. Its patented features include a Sure Align® neck system that helps you play all the way up the neck, while the low-profile velocity satin neck barrel fits comfortably in your hand, and an internal soundboard recurve for added bass response. This gloss guitar features a spruce top with mahogany back and sides, giving you plenty of volume, bright treble, and punchy midrange for that classic Martin sound. It also features an ebony fingerboard and bridge, nickel open gear tuners, Fishman Aura VT Blend or LR Baggs Anthem electronics, and is strung with LUXE BY MARTIN® Kovar™ strings. The SC-18E comes with a molded hardshell case."
