The Kala Copper Resonator Ukulele offers a truly unique visual and tonal palette not found in many other instruments. With an all-brass body and hand-applied antique copper patina finish, these extraordinary instruments are sure to turn heads. At their core, resonator instruments are designed to keep up volume wise with other brass or percussion instruments in a live setting. In place of a traditional soundboard top, the resonator features a brass housing containing an aluminum cone that produces the sound when played, amplifying the natural volume of the instrument—and the metal components add the distinctive shimmer that these instruments are known for. To further add to the live performance capabilities of these instruments, the passive pickup allows you to amplify the sound even further. Each Kala Copper Resonator comes with a plush padded gig bag.
