Sigma JM-SGEFeaturing Mahogany back and sides, the Sigma JM SGE produces a deep and resonant sound with a beautifully warm and musical low end. The large dreadnought body shape ensures brilliant projection loud even when unplugged. The Solid Sitka Spruce top brings out some airy top end character; giving lush chords progressions or finger picked arpeggios all of the beautiful clarity they'd need to cut through in a mix
