Using these D'Addario EJ87S titanium ukulele strings is easy. First, make sure your soprano ukulele is in good condition. Loosen the old strings and remove them. Then, thread the new strings through the bridge and the tuning pegs in the correct order for GCEA tuning. Tighten the strings gradually until you reach the right pitch. When playing, avoid using too much force as it might damage the strings. To keep them in good shape, wipe the strings with a dry cloth after each use to remove sweat and dirt. Store your ukulele in a proper case to protect the strings from dust and humidity. With these simple steps, you can enjoy the great sound of these strings for a long time.
