The LAVA U is a new generation ukulele packed with cutting-edge technology in a small body. It features a bright, natural sound thanks to its unique bio-acoustic design, a playability-focused Unibody design with integrated injection molding, and the L2 mini system with FreeBoost, which allows you to enjoy effects sounds even unplugged. Just turn it on, and you can enjoy reverb, delay, and chorus effects anytime, anywhere, without an amp. The L2 Mini pickup also functions as a microphone to capture percussive sounds like body tapping. The powerful percussive sounds make the ukulele sound even more vibrant.
