It's a cute smiley face! Who can resist owning one of these? The U/SMILE feature is so explicit that it is written directly on the face -- a big Smile on the top which makes me truly happy. The Sengon body, the Jabon neck and the fingerboard and bridge are constructed with choice Mahogany, producing a bright tone that is ideal for a soprano. The geared dolphin style machine heads offer smooth and accurate tuning. The Nubone XB saddle made by GraphTech in Canada reveals the esteem value of this quality ukulele. Aquila strings are also fitted to our ukuleles to produce a fuller, louder and more balanced sound, rich in tonal harmonics.
