?The FIVE.O is small, light-weight, and best of all, specifically engineered to track the uke?s unmistakably unique voice. The system combines a custom version of our award winning Element pickup, a soundhole mounted volume control and a miniature endpin preamp powered by a 3V battery. We radically miniaturized our design so that the complete system weighs less than a 9V battery and tucks away neatly inside of the small instrument for a non-invasive installation. The pickup also features a pull guide to facilitate faster installations.   Custom Element pickup Easy-in pull guide Miniature endpin preamp Soundhole mounted volume control Super light weight Battery type: single 3V Battery life: 300+ hours
