Martin Era Phosphorus Bronze Treated Acoustic Guitar Strings Medium (13-56)

Martin Era Phosphorus Bronze Treated Acoustic Guitar Strings use special materials and coatings to help your guitar sound bright and stay strong. These strings mix a strong core with a thin outside wrap made of bronze. The bronze gives each note a clear ring that stands out in a group. Martin uses its Lifespan treatment so the strings fight off rust and last longer, even after lots of playing. The flexible core bends easily, so your fingers don’t get tired as fast. Each string has silk wrapped around the ball end, which protects old guitars and feels smooth when you change strings. The Artist Light version uses a different core that matches the sound of Jason Isbell, who has won six Grammy awards.

Martin Strings Add Comfort and Lasting Tone to Playing

Musicians who play a lot and want strings that stay fresh will notice the difference with these bronze strings. The Lifespan coating helps keep sweat and dirt from making the strings dull. Flexible cores let you slide and bend notes without hurting your fingers. The silk-wrapped ball ends help old guitars by stopping wear at the bridge. If you want each note to sound clear and have fewer breaks, these strings make playing easier and help your music stand out.
