Deering’s patented Smile Banjo Bridge is created with a curve on the bottom to fit into the natural curve created on a banjo head by the bridge when under string tension. This relieves the stress found in a traditional bridge allowing the Smile Bridge to vibrate without constriction. The result is an instantly fuller and more expressive mid-range, less constricted low frequencies, and a wonderful balance across all strings. • MFSKU 5/8 Smile
