The Deering Smile Banjo Bridge is a curved banjo bridge that fits into the natural curve on a banjo head when under string tension which improves tone, tuning and intonation.
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 midrange, less constricted low end frequencies, and a wonderful balance across all strings.
5-string - 5/8th - standard size flat
