I-M-14TB

National Reso-Phonic M-14T 'ThunderBox' Resonator Guitar

Includes Hardshell Case

The National M-14T ‘ThunderBox’ Resonator Guitar takes the celebrated M-14 series to bold new heights, delivering greater volume, punch, and low-end response. With its deeper 4" body, the ThunderBox produces a thunderous yet balanced sound that resonates with warmth and clarity. Its carefully selected tonewoods and expert craftsmanship ensure the unmistakable character that players expect from National, while offering a livelier, woodier twist on the classic resonator voice.

Built for performance as well as playability, the ThunderBox features a solid mahogany neck paired with an ebony fingerboard for smooth, responsive fretting. Mother-of-pearl inlays add a refined touch, while the satin polyester finish highlights the natural beauty of its construction. Complete with a National Deluxe Hardshell Case, this guitar is as road-ready as it is stage-worthy. The ThunderBox is designed to inspire musicians seeking a resonator with depth, power, and unmatched tonal personality.

We endeavour to show the actual instrument in stock whenever possible, but the guitar in stock may differ slightly from the one shown on our website. 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.

Please note that returns will not be accepted for variations in timber grain /  colouring, finish variations and parts colouring, unless there is a fault with the instrument. If you have any questions at all regarding an instrument's appearance, just drop us a line - we're always happy to send photos, and if we have more than one instrument in stock you'll be able to choose the exact guitar that you receive!
