NY steel core with Fusion Twist steels
Inside each XS nickel string is a NY Steel core — the same as you’ll find on a set of your favorite NYXLs or XTs electric guitar strings. This angular core gives the wrap wire more surface to grab on to, resulting in better tone and intonation. Plus, XS strings also feature D’Addario’s Fusion Twist technology, a process that prevents slack in each string’s winding, ensuring it stays more in tune and lasts longer.
Engineered for graceful aging
D’Addario XS sets aren’t your ordinary coated guitar strings. Both the wound strings and plain steels feature groundbreaking thin film coatings. This eliminates that awkward stage common to other coated strings where your bottom strings far outlast your top strings.
