12-54 Med-Light 80/20 Bronze SKU: 21254 Product Description 80/20 Bronze wound strings are often called old-school, vintage and/or bright bronze and were the most popular (only) alloy used to make acoustic strings until the introduction of phosphor in the early Seventies. 80/20 bronze wire is made from 80 percent copper and 20 percent zinc. 80/20 bronze provides balanced highs and lows with a slight increase in mid-range that seems the make the notes cut-through a little more.
