Designed with player comfort in mind, this guitar features a low-profile mahogany neck with a vintage-style feel, along with a Micarta fingerboard for smooth playability. The 1-3/4" nut width provides ample room for fingerpicking and strumming alike.
Equipped with a Fishman Sonitone pickup system, complete with soundhole Volume and Tone controls, this guitar is ready to hit the stage or studio. The Grover Nickel Open-Geared tuning machines ensure precise and stable tuning, while the high gloss finish enhances its overall beauty.

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.
If you're after a particular look, feel free to email us at info@acousticcentre.com.au or send us a message through our chat service to request photos of the actual guitar in stock. We are more than happy to send through pictures of all in-stock guitars, to make your choice easier.
