At Kala we do our best to provide high quality string options for our players. For our Kala Elite USA Ukulele String Set, we’ve teamed up with one of the best of the best—Worth Ukulele Strings. Worth and Kala have gone to great lengths to optimize this set for Kala ukuleles. The sound of these 100% fluorocarbon brown strings can be described as warm, mellow, and astonishingly clear. They have a clean, natural sustain and plenty of projection. When we customized the gauges of these strings, we took the lead from Kala artist, Corey Fujimoto, creating a thicker C string with the intention of delivering a more robust presence in the low end of the instrument. This makes the entire set sound richer, fuller, and more consistent from string to string. Worth Ukulele Strings is a Japanese company that is well known for their fluorocarbon string material that enhances intonation, note clarity, and sustain.
