Solid Spruce and Mahogany Tone

The Sigma DM-18 brings together a solid Sitka spruce top with mahogany back and sides to deliver a balanced, versatile acoustic tone.

The spruce top provides clear definition, excellent dynamics, and sparkling brightness, while the mahogany adds warmth, depth, and resonance. Together, these tonewoods create a rich, responsive sound suited to a wide range of musical genres and playing styles from deep-rooted folk blues to contemporary indie styles.

Powerful Dreadnought Sound

The Sigma DM-18 features a traditional D-14 fret dreadnought body, designed to deliver strong projection with a loud voice. The dreadnought body is the perfect size, balancing lows, mids, and highs while projecting its sound forthright.

Comfortable Neck and Fretboard

Built for comfortable, fluid playing, the Sigma DM-18 features a smooth micarta fretboard paired with a mahogany neck. The combination supports easy movement between frets, helping you play with confidence across different styles.
