Sigma GJM‑SGE – Grand Jumbo Acoustic‑Electric Guitar (Sunburst)

The Sigma GJM‑SGE is a bold Grand Jumbo acoustic‑electric guitar designed for players who want volume, power, and stage‑ready performance. Built with a solid Sitka spruce top and mahogany back and sides, it produces deep lows, strong mids, and sparkling highs with impressive projection. The low‑profile mahogany neck, paired with a Micarta fingerboard and bridge, ensures smooth playability and balanced tone. A bone nut and saddle provide clarity and sustain, while chrome diecast tuners keep tuning stable. Equipped with a Sigma preamp system with onboard tuner, it’s ready for both live performance and studio use. Finished in satin sunburst and fitted with D’Addario EXP16 strings, the GJM‑SGE combines classic jumbo tone with modern reliability.
