D'Addario XL Pro Steels Electric Guitar Strings

XL Pro Steels are the brightest and most agressive sounding guitar strings D'Addario makes. Their specialized corrosion-resistant alloy delivers a harmonically rich brilliant high end along with bumped up crunch and sustain.
Engineered with precisely-wound wrap wire on a high-carbon steel hex core, Pro Steels deliver precise intonation and unparalleled consistency, set after set.
