Top: Mahogany, Side/Back: Mahogany, Neck: Okoume, F/b: Walnut, Bag included - The Flight DUS321 is a soprano-sized ukulele. It has a laminate mahogany top, paired with laminate mahogany back and sides, giving it a very warm and resonating sound. Do not let the “sober” look of mahogany fool you, though—mahogany ukuleles, especially those fitted with an arched back like the DUS321, know how to growl!
