We’ve taken the Swamp Ash California U•BASS® with its natural, transparent satin finish and livened it up with a dark, rich, semi-transparent, smooth Black Onyx stain. The Swamp Ash grain, that ranges from straight cut lines to curly loops, can be seen beneath the layer of color. The grain pattern takes on the black stain and becomes mono-chromatic. This makes each uniquely patterned U•BASS a one-of-a-kind piece of art!

Every California U•BASS boasts exceptional low-end and outstanding craftsmanship which makes this series a perfect fit for next-level bass players. This U•BASS is handmade in California using custom-made parts, including the Kala + LR Baggs preamp that delivers a huge low end and tonal versatility. This custom preamp lets the California U•BASS produce the deep signature bass tone that the U•BASS is known for, while adding clarity in the mid-range and upper registers. Plug-in and experience the full range of what the U•BASS has to offer!

String Disclaimer

All California U•BASS® are meant to be strung with proprietary, polyurethane Road Toad Strings. Kala Round Wounds, Flatwounds, and High C Strings will not work on the California Solid Body U•BASS.

Beautiful Little Bass

Beautiful little black bass. Black swamp ash California U-bass. Very well constructed and flawlessly finished instrument. Easy to handle and play. Really does sound like an upright bass. Perfect for acoustic sets, blues, folk, gospel, or jazz. I’m an old player with arthritis, so I’m thrilled to have a bass that sounds so good yet is easy on the hands. It is tremendous. I HIGHLY RECOMMEND IT!
