Using these Ernie Ball Earthwood acoustic guitar strings is easy. Just replace your old strings one by one, starting from the thinnest to the thickest. When you're tuning them up, do it slowly to avoid breaking the strings. As for maintenance, wipe the strings with a clean cloth after each use to remove dirt and sweat. This will help keep the mellow, ringing sound for longer. Also, store your guitar in a dry place to prevent the strings from rusting. If you notice the sound getting dull, it might be time to replace the strings with a new pack from your 3 - pack set.
