Sigma SDJM-18

The Sigma SDJM-18 is an all-solid, slope-shoulder dreadnought built for strong rhythm work, flatpicking, country, folk, bluegrass, and acoustic rock. Its AA-grade solid Adirondack spruce top is paired with solid mahogany back and sides, giving the guitar a direct, responsive character with clear note separation. The mahogany neck has a low-profile shape, a 25.4-inch scale, and a comfortable 44.5 mm nut width. Traditional details include a dovetail neck joint, ebony fingerboard and bridge, bone nut and saddle, and nickel Grover side-mounted tuners with butterbean buttons. A polished gloss finish with aging toner completes its understated vintage appearance. The guitar includes an SSC-D softshell case.
