D’Addario’s Half Round strings will give you the sound and tension of regular round wound strings but with the feel of semi-flat strings. Roundwound, stainless strings are precision ground with D’Addario’s exclusive, centerless grinding system for a string that gives you the bright, clear sound of round wounds and the ease of playing and diminished finger noise of flat wound strings. Customers have called these specialized strings the “secret of the pros” for their combination of roundwound and flatwound qualities. Their smoother surface is fantastic for a slide guitar as well. You can find Half Rounds in gauges from super extra light (.008 - .039) to jazz lite (.012 - .052). If you are looking for heavier gauges, try D’Addario's EJ22 XL Nickel Wound or ECG26 Chromes Flat Wound.
