D'Addario EXL120 Electric Guitar Strings are made from Nickel Plated Steel, which provides a softer, smoother surface that's faster and easier on the fingers than stainless steel, yet has a similar dynamic sound and output.
The nickel surface virtually eliminates finger noise and improves playability. D'Addario uses computer controlled monitoring to ensure they have precise engineering that produces unparalleled consistency.
Here in a Super Light gauge, this set has thicknesses of 9, 11, 16, 24, 32, 42.
