A warm, understated Sigma DM-15 from the 15 Series, built around a D-14 fret dreadnought body with a solid mahogany top and mahogany back and sides. The all-mahogany construction and satin finish give it a clean, workmanlike character, while the low-profile mahogany neck, 25.4-inch scale and 42.9mm nut make it a comfortable everyday acoustic. Practical details include a dovetail neck joint, Micarta fingerboard and bridge, bone nut and saddle, Grover die-cast tuners and a two-way truss rod.
 
This preloved example is in very good condition with only light signs of previous use. A small mark to the rear of the neck is shown in the photographs. A tidy, well-specified dreadnought with serial number 130814179.
