XL Nickel Wound, D'Addario's most popular electric guitar strings, are precision wound with nickel plated steel onto a high carbon hexagonal steel core. The result is strings with long lasting, distinctive bright tone and excellent intonation, highly versatile and ideal for the widest variety of guitars and playing styles. The EXL110W regular light gauge combines the most popular XL110 gauging with a wound 3rd string and offers great tone, flexibility and long life. The wound 3rd makes these strings ideal for acoustic players who like to double on electric rhythm guitar. Like all D'Addario guitar strings, they come in environmentally friendly corrosion resistant packaging for freshness in every set.
