Using these D'Addario 80/20 Bronze acoustic guitar strings is easy. First, loosen the old strings and remove them from your guitar. Then, thread the new strings through the bridge and tuners. Tune the strings to the right pitch. When you're playing, you'll notice their bright and deep tone. To keep them in good condition, wipe the strings with a clean cloth after each use. This helps remove dirt and sweat. Store your guitar in a dry place to prevent the strings from rusting. And if you notice the tone getting dull, it's probably time to change the strings.
