The Sigma GJM-SGE Electro Acoustic, Sunburst offers a solid top and 14-fret grand jumbo body combined with a classic yet sonically-versatile tonewood combination and a built-in Sigma preamp with tuner, perfect for the performing musician. With a solid sitka spruce top and a mahogany body, the Sigma GJM-SGE produces a broad dynamic range with a clear, powerful response, as well as delivering a rich resonant warmth and plenty of emphasis within the mid-range. Additionally, the Sigma’s real bone nut enhances the guitar’s tone further by adding more resonance and sustain. Furthermore, the Sigma GJM-SG100 has a curvaceous 14-fret grand jumbo body which is spectacularly well-balanced across the tonal spectrum and is able to accommodate both fingerstyle techniques and meatier chord work with equal ease. This sonically-powerful electro acoustic from Sigma also comes equipped with Sigma’s own preamp system, offering basic sound tweaking for live, studio and rehearsal environments.
