• Copper Bronze Make

Introducing Red. The first brand of Copper Bronze acoustic guitar strings. With the highest copper content of any string material - more than 80/20 and more than phosphor bronze -RED Strings gives acoustic guitars precise articulation, louder sound, greater projection and a warmer, richer tone from the moment you tune them up. There hasn't been a significant new material introduced for acoustic guitar in 35 years.
