Sigma 000M-15S+ Acoustic Guitar w/ Solid Mahogany Top

The Sigma 000M-15S+ brings mahogany warmth to a player–friendly concert body shape, combining solid mahogany top construction with a 12–fret 000 design that balances rich midrange projection with comfortable fretting access. Dovetail neck joinery and a low–profile mahogany neck deliver structural stability and easy playability across the 645 mm scale length. This model targets fingerstyle players and singer–songwriters who prioritise tonal warmth and tactile comfort over aggressive volume, offering solid–top resonance at an approachable price point.

Construction centres on a solid mahogany top paired with mahogany back and sides, finished in satin lacquer that allows the wood to breathe and resonate freely. The 44.5 mm nut width provides ample string spacing, while bone nut and saddle components maximise harmonic transfer. Micarta fingerboard and bridge offer durability and consistent performance across varying humidity levels. Grover nickel side–mount tuners with butterbean knobs ensure stable tuning, and a two–way truss rod permits precise neck relief adjustment. D'Addario EXP16 strings come fitted as standard.
