Using these Ernie Ball Earthwood 80/20 Bronze Acoustic Guitar Strings is easy. First, remove the old strings from your guitar. Then, carefully thread the new strings through the bridge and the tuning pegs. Make sure to tune them up slowly to avoid breakage. As for maintenance, wipe the strings with a clean cloth after each use to remove dirt and sweat. Also, keep your guitar in a dry place to prevent rusting. If you notice any signs of wear or if the sound quality starts to decline, it's time to replace the strings.
