Each cut of wood selected for the Hawaiian Koa California U•BASS® features its own unique patterns and hues, making every creation a highly figured, one-of-a-kind masterpiece. Koa's warm golden tone shines through the varying streaks, lines, and dimples of the top's figuring in a perfect complement to the natural Ash body of this short-scale bass. Every California U•BASS® is handcrafted at the Kala USA Workshop in Petaluma, California. Boasting exceptionally deep lows and outstanding craftsmanship, it makes a perfect fit for the next-level bass player. Specialty components have been added to deliver the huge low end and versatility this series is known for. Graph Tech’s HeliumX® Bridge with Ghost® Saddles provides adjustability for flawless intonation, and the LR Baggs custom preamp produces incredible bass tone with clarity in the mid-range and upper registers. Each California U•BASS® comes with a Deluxe Padded Gig Bag.
