The L.R. Baggs FIVE.O ukulele system is small, light-weight, and best of all, specifically tuned to track the ukes natural dynamics and its unmistakably unique voice.The system combines a custom version of the award winning Element undersaddle pickup with a miniature endpin preamp, soundhole mounted volume control and is powered by a 3 Volt coin cell battery. The entire system weighs less than one 9 Volt battery and tucks away neatly inside the small instrument for a non-invasive installation.The pure, all-discrete electronics are voiced for the most accurate frequency response you have ever heard, so plug into the FIVE.O and enjoy the performance you have been waiting for.
