Vintage Vega Banjo Resonator 1920s for 10-15/16". This is an original, old resonator from the Vega Co. of Boston, Mass. It was used on the Vega banjos with various rim diameters. This one will accommodate a rim up to 11" in diameter. The resonator is in very good condition considering its age. This resonator would be ideal for converting your open back Vega to a resonator to give it more volume. This would be especially useful for a 17-fret banjo that was sold as an open back banjo. These would be used for Irish style playing so the added volume of having a resonator.
