Understated yet elegant, the natural look of the Big Leaf Maple California U•BASS® is sure to turn heads. Literally 'going against the grain' is what creates the figuring that can be present in Big Leaf Maple. From the tiger stripes of flame maple to the watery ripples of quilted maple, a captivating display of undulating chatoyant variations awaits. 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.
