I bought these to replace the big rubber band strings on my fretless electro-acoustic ukulele. An immediate improvement. I can now slide along the string, the friction of the rubber string prevented this previously. The smaller diameter of the strings gives slightly greater space between them, so less accidental muting. I am going to have to make some small adjustments to the nut to account for the smaller diameter, maybe even replace the nut, but the improvement brought by these strings is worth it.
