These D'addario EZ930 American Bronze acoustic guitar strings are made from 85/15 Bronze and are shown here in medium gauge 13-56. The 85/15 Bronze combination will give a crystal clear brightness and clarity but with the bottom end, loud projection and longer life of Phosphor Bronze. This set is excellently rounded and balanced with very good intonation thanks to the precision wound wrap wire.
Medium gauges will give you a loud sound and are ideal for heavy strumming, open tunings and slide playing. The tight feel this gauge gives allows you to play nice and hard and it'll stay in tune well.
The individual string thicknesses are: .013, .017, .026, .036, .046, .056.
