Get to know them!

Get ready for a huge bass sound in a not-so-huge package with the Kala U-Bass Spalted Maple. Owing to its compact 20.812” scale, this Kala U-Bass Spalted Maple is a perfect travel companion that’s ideal for playing around the campfire, busking in the streets, and bringing on vacation, so you don’t have to miss a single day of playing! Featuring an eye-grabbing spalted maple body and top, a mahogany neck, and a rosewood fingerboard, the Kala U-Bass Spalted Maple is exceptionally balanced with a room-filling sound that belies its diminutive size. And, when it’s time to plug-in, you’ll be blown away by its natural-sounding U-Bass electronics. Bass players at Sweetwater sure were! For a unique bass with a tone that doesn’t quit, check out the Kala U-Bass Spalted Maple.

Exquisite combination of tonewoods

This U-Bass has a gorgeous spalted maple body, which exhibits a bright tone with great balance and projection, along with tight bass and superior note separation. The U-Bass Spalted Maple comes outfitted with a satin-finished mahogany neck capped with a rosewood fingerboard that feels great in your hand and provides an incredibly comfortable playing experience.

Special strings, special sound

The secret behind the big sound of the Kala U-Bass is almost as cool as its small, ultra-portable format. It comes from the combination of the right tonewoods and Aquila's Thunderblack polyurethane strings. These lightweight, large-diameter strings provide plenty of low-frequency oomph, which resonates with a deep, rich, and wooden quality that's reminiscent of the coveted upright sound yet colored with a uniquely musical U-Bass quality all its own.

Packed with premium appointments

Other standout appointments that add to the rich sound and stunning looks of the U-Bass Spalted Maple include a Graph Tech NuBone nut and rosewood saddle. Custom black die-cast tuning machines keep you in tune and add a nice visual enhancement. Finally, U-Bass electronics kick out great amplified tone when you plug in, complete with built-in volume and tone controls, and an onboard tuner — no more fiddling with clip-ons or tuner pedals.
