Frequently Asked Questions

The amber tone is achieved through a tinted finish; it's very thin and doesn’t significantly alter the fundamental tone, but can add a touch of warmth.
The neck profile is a modified low oval, which is generally comfortable, but players with very large hands might find it slightly snug; it's a standard Martin shape, though.
While the Ambertone doesn't have the absolute top-tier appointments of the higher-end models, the build quality is excellent, and the materials are still premium—a great value for the price point.
