Martin Authentic Phosphor Bronze Strings
In the fall of 2018, Martin replaced their Traditional Budget range of Phosphor Bronze Guitar Strings with this new Authentic line which is based on their premium SP range.
Designed with the performer in mind, Martin Authentic strings begin with the highest tensile-strength core wire which is tin plated to stop corrosion. The core is then wrapped with the highest quality phosphor bronze to bring you crisp highs and bell like basses. These strings move you out of the budget range with a product made for pros.
