Using these D'Addario XT electric guitar strings is easy. First, loosen the old strings on your 6 - string electric guitar and remove them. Then, thread the new strings through the bridge and the tuning pegs, and tune them to your desired pitch. When you're playing, you'll notice the great tone right away. As for maintenance, try to wipe the strings down with a clean cloth after each use to remove sweat and dirt. This will help keep the corrosion - resistant treatment working well. And be careful not to over - tighten the strings, as this can cause them to break. With proper use and care, these strings will serve you well for all your electric guitar playing, no matter what genre you're into.
