The D'Addario EXL115 Nickel Wound medium-gauge electric strings are a great choice for players looking for a fuller, meatier tone. Precision-wound nickel-plated steel envelops D'Addario's tried-and-true high-carbon steel core for a balanced tone from E-to-E and long lifespan. These .011-gauge strings are a perfect happy medium for blues, jazz, and rock guitarists who don't get enough bottom end out of lights and don't feel comfortable on .012s and higher.
