D’Addario’s XL strings are round wound with nickel-plated steel wrap wire. They produce a bright, true sound with no premature fret wear.
Each string is twisted to perfection right down to the three neatly wrapped "lock twists." And those lock twists help keep our plain steel strings from unraveling or breaking prematurely. Each and every spool of precision drawn high carbon steel wire we use goes through three quality control tests before it hits our inventory shelves.
Pioneering innovative string design has been a D’Addario family tradition for nine generations. Most guitar players don’t realize that the inner core wire in all D’Addario steel strings is made from carefully drawn, hexagonally shaped, high carbon steel wire. The six "edges" of the core wire bite into the softer wrap wire, securing it all along its length. The hexagon core is just one of the reasons D’Addario strings are "Better by Design." Hexagonally shaped high carbon steel core wire. Core wire edges dig in to the wrap wire to insure a tight bond between the core and the wrap wire.
