The Sigma GJA is an acoustic guitar in jumbo shape with solid spruce top in vintage sunburst look and maple back & sides. The maple body produces a bright and present sound that harmonizes wonderfully with the size of the jumbo body and delivers a pronounced bass with punchy mids - perfect for strumming and predestined for singer-songwriters.
With the in-house Fishman pickup system, you'll be ready for any gig. To give you the best acoustic sound possible, the preamp has volume and tone controls and a built-in tuner.
