9-46 12-String Light PhosPhor Bronze Acoustic Guitar String Set
Phosphor Bronze wound strings were introduced in the early Seventies and have become the most popular acoustic string. Phosphor bronze wire is made from approximately 92% copper, 7% zinc and 1% phosphorous. Phosphor Bronze provides nice highs and lows with pleasant subtle overtones. Phosphorous is used to help reduce tarnish and corrosion.
All of curt's strings are great. I use Them on all my guitars. They keep a good clean sound for a long time.
