D'Addario EXP16 Coated Phosphor Bronze Acoustic Guitar Strings, Light, 12-53

Among D'Addario's most popular acoustic guitar strings are round wound phosphor bronze. Slightly softer than 80/20 bronze, round wound phosphor bronze strings are synonymous with warm , bright, and balanced acoustic tone. Made with corrosion-resistant metal wrapped around a hexagonal steel core, these strings will impress with their longevity and superior tonal characteristics. D'Addario was the first to manufacture these strings, starting in 1974, and their popularity and durability have been immediate. The EXP line features D'Addario's patented, life-extending D'Addario coating. The polymer coating is applied to the wrap wire BEFORE it is wound onto the steel core, resulting in strings that sound and feel like uncoated, while having four times the durability.
