Sigma

Sigma Guitars is the respected acoustic guitar brand originally launched in 1970 by C.F. Martin & Co. to offer high-quality, high-value acoustic instruments. Today, Sigma continues this legacy, offering an extensive range of guitars that faithfully replicate classic Martin body styles and tones at accessible price points, as well as other classic models. The lineup includes all-solid wood models in the Standard Series and high-value, solid-top models in the Road Series. Key models include accurate takes on the Dreadnought (DM-18 and DM-28), the OM (Orchestra Model), and the smaller 000 (Auditorium) series. Sigma guitars are praised for their superb playability, quality construction, and inclusion of features like bone nuts and saddles. A Sigma Dreadnought or OM provides the musician with a reliable, great-sounding acoustic guitar that offers the classic shapes and tonal characteristics of its prestigious heritage.
