The Sigma 000M-15 is part of the Sigma 15 Series, a range created for players who want the warm, characterful voice of an all mahogany acoustic. With its solid mahogany top and matching mahogany back, sides and neck, this model delivers the rich, woody tone that made vintage all mahogany acoustics the go-to alternative for players seeking something different from the brighter spruce-topped designs of the past.

The 000 body shape offers a comfortable, mid-sized feel with excellent balance and clarity. Its focused low end and strong midrange make it ideal for fingerstyle, blues and folk, while the satin finish and single ring rosette add a touch of understated elegance. The dovetail neck joint ensures a traditional, resonant connection between neck and body, enhancing sustain and overall tonal response.

A mahogany neck with a low profile carve provides a smooth, inviting feel, paired with a micarta fingerboard and bridge for stability and consistency. Bone nut and saddle improve clarity and tuning accuracy, while the chrome Grover diecast tuners offer reliable performance. The guitar comes factory-fitted with D'Addario EXP16 strings, giving it a balanced, articulate voice straight out of the box.

The Sigma 000M-15 is a simple, elegant and great-sounding acoustic that captures the charm of classic all mahogany guitars while offering modern reliability and playability.
