Premium Lifespan Protection

Martin’s patented Lifespan treatment helps guard the strings against corrosion and build-up, so your tone stays clear and musical for longer. This means fewer string changes, more consistent sound between sessions and a guitar that feels ready to play whenever inspiration strikes.

Flexible Core Comfort

The Flexible Core construction is designed to enhance fretability and comfort, making bends, vibrato and extended playing sessions noticeably easier on your hands. You get a responsive, expressive feel that encourages more dynamic playing without having to fight the strings.

Silk-Wrapped Ball Ends

Silk-wrapped ball ends provide a premium finishing touch that is especially considerate of vintage and more delicate instruments. The silk helps cushion the contact point at the bridge and reflects Martin’s heritage of meticulous, handcrafted string making.
