Lightweight, compact and sonically flexible, the KNA UP-2 is a stick-on guitar pickup that enables acoustic musicians to amplify their instrument and control volume from the stage. This versatile passive piezo pickup attaches safely and securely to almost anything that vibrates - while the UP-2 may be intended as a surface-mount guitar and ukulele pickup, it also works well on harp, drums and percussion. Features: Install with no modification - Simply stick the pickup on your instrument’s soundboard. Onboard volume control - Players have control over their output signal while onstage or in the studio, right from the pickup-mounted volume control. Wood housing - The laminated Birch-encased piezo pickup features a sophisticated and classy Mahogany top that is incredibly lightweight, and achieves superior tonal sensitivity. Natural sound - UP-2 uses a passive design that reproduces the organic tone of the instrument without the requirement for a battery. Complete installation set - The pickup includes a double-sided adhesive disc, enough PowerTack adhesive for several applications, and a removable 1/8 to 1/4 cable that enables the pickup to stay in place during storage.
