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 EXL120-8 super light gauge is the 8 string version of one of D'Addario's bestselling sets and offers a combination of great tone, flexibility and long life, with a lighter gauge for faster shredding and extra bite. A standard for many electric guitars, and like all D'Addario guitar strings, they come in environmentally friendly corrosion resistant packaging for freshness in every set.
