D'Addario Flatwound Mandolin are constructed using a complex combination of interlocking underwindings on a hex core, which builds the foundation for a delicate outer flat (ribbon) winding. This unique design allows the strings to vibrate freely, creating a true, clear sound and an ultra-smooth feel. Created for jazz, classical and folk players, they deliver unparalleled comfort for playing closed position fingerings and along the fretboard.
