Sigma GJR‑SG300 – Grand Jumbo Acoustic‑Electric Guitar

The Sigma GJR‑SG300 is a powerful Grand Jumbo acoustic‑electric guitar crafted for bold projection and rich tonal depth. Featuring a solid Sitka spruce top and Indian rosewood back and sides, it produces deep lows, articulate mids, and shimmering highs with excellent dynamic range. The mahogany neck with walnut strip, paired with a Micarta fingerboard and bridge, ensures stability, smooth playability, and clear sustain. A bone nut and saddle enhance tonal precision, while Grover gold “pyramid” tuners add a touch of elegance. Equipped with a Fishman Sonitone pickup system, it delivers natural amplified tone for stage or studio. Finished in polished gloss with aging toner (antique natural), the GJR‑SG300 comes with a softshell SSC‑GJ case and D’Addario EXP16 strings.
