Hard on electric guitar strings? Wadsworth Music guitarists are excited about D'Addario NYXL strings because they sound great, bend farther, and stay in tune better - than just about anything else we've played. D'Addario uses a high carbon steel core with a unique "fusion twist" process for the plain strings. NYXL's reformulated nickel plated string windings have increased magnetic properties that give you higher output and juiced midrange for greater presence and crunch. If you're dissatisfied with your electric guitar strings, give D'Addario NYXL strings an audition. You'll be impressed.
