Its large body delivers exceptional projection, making it ideal for solo performers and ensemble settings alike.

A low-profile mahogany neck with a walnut center strip offers excellent playability, while the polished gloss finish and gold Grover "Pyramid" tuners add a premium aesthetic. Onboard Fishman Sonitone electronics make it easy to take this guitar from the couch to the stage, delivering natural, clear amplified tone with simple plug-and-play operation.

Materials used can look different from guitar to guitar, including timber grain and colour, parts colours and finishing. If an instrument is a one-of-a-kind or preowned guitar, the picture will always be of the actual guitar in stock, but production models may have slight variations to the picture shown.
