Using these Ernie Ball Earthwood guitar strings is easy. First, loosen the old strings and remove them from your guitar. Then, thread the new strings through the bridge and up to the tuning pegs. Tune the strings to the right pitch. Remember, when you're changing the strings, be gentle to avoid breaking them. For maintenance, after each use, wipe the strings with a clean, dry cloth to remove dirt and sweat. This will keep the strings sounding great and also extend their lifespan. Don't expose the strings to extreme humidity or temperature, as this can damage them. With proper care, these strings will provide you with a long - lasting, mellow sound for your acoustic guitar.
