This three-pack of D'Addario EJ17 phospor bronze medium 13-56 acoustic guitar strings features a hex core made from high-carbon steel for strength. The strings offer heavier tension, which produces a bold, resonant tone while standing up to heavy strumming and flat-picking. The corrosion-resistant package helps to protect the strings from damage and ensure long-lasting quality.
