Our new EH Strings allow you to capture every nuance of your playing style with lightning fast playability. Made of a pure nickel wrap with a specially-selected stainless steel, these sweet-sounding round wounds are truly like no other strings you've played. Not only do they last longer and stay in tune longer, but we think they're the best sounding strings ever made. Available in 9s, 10s and 11s.
