I needed new strings after adding an under bridge pickup to my tiny ukulele travel, and 2 other brands were too "tight" and the uke kept going out of tune, also sounded awful, so I looked for mellow strings and this came up several times. Now, not only the ukulele doesn't go out of tune anymore, but it sounds better than it ever did, nice vintage sound. Also black strings look cool, although that s not the important part. These are my new favorite strings now.
