Custom light hybrid 6 string set for acoustic guitar, ideal for players who want the depth and projection of light gauge bottom strings, but slightly less tension on the high strings for easy bending. Strings are wound on a hexagonally shaped, high carbon steel core, resulting in long lasting, bright sounding tone with excellent intonation. 80/20 Bronze winding, commonly referred to as brass, is the original acoustic string alloy and popular for recording due to their crisp, deep and projecting tone. Package of the set is environmentally friendly and corrosion resistant so it keeps strings always fresh. D’Addario strings are made in the U.S.A. Gauges: .011, .015, .022w, .032w, .042w, .052w.
