Balanced 9s by Stringjoy Super Light Nickel Electric Guitar Strings All of our electric guitar strings are handmade in the USA from American nickel alloy windings and thick, hexagonal steel core wire. Once you find the perfect strings for you, we’ll inspect, coil, and package them by hand. Soon you’ll be playing the best strings you’ve ever played — the perfect set for your playing style — and you’ll never want to go back to playing the same strings everybody else gets off the rack. The most frequent comments we hear about our string sets: • How balanced they feel across the fretboard • How warm and consistent they sound fresh out of the pack • How well they hold tune right from the first time you tune up
