The Satin Mahogany Series is Kala's flagship series and has become an industry standard since they introduced it in 2005. These ukes are made of mahogany which offers a full, rich sound. The Series comes in a beautiful satin finish that gives it a traditional look to go along with a great sound. This uke makes for a great student instrument and will stand the test of time. Offering a classic tone wood combination, the KA-15S-S Soprano Ukulele pairs the satin-finished mahogany back sides with a spruce top. Other features include a mahogany neck, a rosewood fretboard, a GraphTech Nubone XB nut, and open-geared tuners.
