Top: Walnut, Side/Back: Abs, F/b: Abs; Bag - Flight Travel Ukuleles have been acclaimed for their great sound, playability, durability, and value. Flight Concert Travel Ukuleles (TUC) have a slightly larger body and a slightly longer fretboard than the Soprano Travel Ukulele, resulting in a larger sound--all the great qualities of the TUS, but bigger. Players with larger hands will enjoy the extra room on the fretboard. The Flight TUC-50 uses laminate walnut for the sound board. Walnut is stiffer and denser than Mahogany, so its tone is brighter, as bright as Koa. The beautiful grain, paired with our hand-drawn Salamander design, is popular throughout the world. The ukulele also incorporates an ABS body, neck, fretboard and bridge. The result is a ukulele with low action that is easy to clean and maintain.
