Strings are made of exclusively New York manufactured, high carbon steel alloy and utilize a completely reinvented wire drawing process coupled with a revolutionary “fusion twist” process for the plain steels. The reformulated nickel plated string windings have greater magnetic properties resulting in higher output and enhanced mid-range frequency response for more presence and crunch. 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: .010, .013, .017, .030w, .042w, .052w.
