The GHS Black Ukulele Strings are well loved here on the islands and around the world. They have a strong projection and are full in the higher-mid range. Often companies use the same gauges for soprano/standard and concert, but cut them a little shorter for the standard. GHS just left this set to be used with either soprano size or concert size.
Here is a video demo of 4 different brands of concert strings -This GHS set is one of them!
