Lightest and smallest stick-on KNA guitar pickup, the versatile UP-1 passive piezo attaches safely to just about anything that vibrates. In addition to being a surface-mount guitar pickup, UP-1 can be used for harp, drums, and percussion. The piezo element is encased in laminated birch with an elegant and stylish mahogany top. The lightweight assembly offers maximum tonal sensitivity. UP-1 has a passive design that reproduces the natural sound of the instrument with no need for a battery. The pickup comes with a double-sided adhesive disc and enough PowerTack adhesive for multiple applications, and a detachable 1/8" to 1/4" cable that allows the pickup to remain in place during storage.
