SIGMA GUITARS Dm-18

DM-18: The "Dreadnought" Spirit in a Timeless Wood Configuration

The DM-18 is part of the great tradition of folk guitars in the dreadnought format, a standard appreciated for decades for its breadth and acoustic power. The combination of solid spruce and mahogany is among the most sought-after: it offers a clear response, good versatility, and an immediately musical character, whether played with a pick or fingerstyle.

For Whom and Which Styles?

Thanks to its dreadnought size and solid top, the DM-18 is well suited for motivated beginners as well as intermediate players looking for a responsive and expressive folk guitar. It excels particularly in folk, pop, country, chanson, and energetic strumming, while remaining convincing in picking when clear and articulated notes are desired.

Sound Characteristics

The solid Sitka spruce top provides clarity, attack, and beautiful dynamics: the harder you play, the more the guitar responds with breadth, making it an excellent foundation for accompaniment. The mahogany back and sides enhance the midrange and deliver a warm tone, with well-controlled lows and present highs without harshness. The dreadnought shape favors generous projection and comfortable sustain, while the bone nuts contribute to better note precision and a more "alive" resonance sensation.
