Sigma JM-SG45
The Sigma JM-SG45 is a professional-grade acoustic guitar built for players seeking quality tone and playability. Featuring a solid Sitka spruce top paired with mahogany back and sides, this instrument delivers warm, resonant sound with excellent projection. The slope shoulder D-14 fret body design offers comfortable access to higher frets, while the low-profile mahogany neck and Micarta fingerboard ensure smooth, responsive playing. Equipped with a Fishman Sonitone EQ system for amplified performance, GROVER nickel open-gear tuners for reliable tuning stability, and a bone nut and saddle for superior tone transfer, the JM-SG45 combines traditional craftsmanship with modern electronics. Includes a Sigma SSC-D gigbag for convenient transport and protection.
