Banjo Pickup Leveraging the unitary design that made their Violin Pickup a staple for thousands of performing musicians, L. R. Bags has molded their same miniature vibration sensor directly into a 5/8 in. banjo bridge. As an integral part of the bridge, the pickup captures inherent characteristics of the instrument fluently at the source without altering any acoustic properties. It comes with a fully custom jack and mounting system engineered to be reliable, easy to install and aesthetically compatible with the finest instruments.
