Ernie Ball's nickel wound electric guitar strings are crafted from nickel-plated steel wire wrapped around a tin-plated hex-shaped steel core wire. The plain strings are made of specially tempered tin-plated high carbon steel. These strings offer a well-balanced tone for your 7-string guitar. The gauge set includes .010, .013, .017, .026, .036, .046, and .056.

Using these Ernie Ball guitar strings is easy. First, loosen the old strings and remove them from your 7-string electric guitar. Then, thread the new strings through the bridge and the tuning pegs. Tune each string to the right pitch. When it comes to maintenance, wipe the strings with a clean cloth after each use to remove sweat and dirt. This will help keep the strings sounding great for longer. Also, avoid exposing the strings to extreme temperatures or humidity. If you notice the tone starting to fade or the strings getting dull, it's time to replace them.
