Sigma was established in 1970 by C.F. Martin & Co. as their first line of quality imported guitars. Now owned and distributed within North America by St. Louis Music; Sigma is reborn and leading the way in high quality, traditionally styled acoustic guitars.

The Sigma sound is open and powerful with more than a generous nod to the vintage tone we know and love. Sigma guitars are balanced and responsive and deliver signature bass with sonically true mids and trebles.

Traditional Dreadnought and OM shapes are available in Sitka/Mahogany and Sitka/Rosewood options. Acoustic electric options with premium EQ’s and pickups from B-BAND are also available in each model.

Today’s Sigma guitars deliver classic tone with superior modern dynamics.
