Using these D'Addario EJ65S soprano ukulele strings is easy. First, tune your ukulele to ADF#B. You'll notice right away how smoothly they feel under your fingers and how they respond to even the gentlest strums. When you play, you'll enjoy the bright and warm tones they produce. For maintenance, after each use, wipe the strings with a soft cloth to remove sweat and dirt. This will keep the strings sounding great for longer. Also, avoid exposing the ukulele to extreme temperatures and humidity as it can affect the strings' performance. If you notice the tone starting to dull, it might be time to replace the strings.
