At KLOS Guitars, we built our Full Carbon Bass Ukulele for players who need a bass ukulele that’s both rugged and refined. This all-carbon instrument delivers stable performance in any climate, with clear projection and a rich, full tone that holds up on stage, in the studio, or out on the road. It’s a compact travel bass that feels like a pro-level acoustic-electric ukulele. In fact, it even includes an onboard piezo preamp and tuner for instant plug‑in convenience.
We use a one-piece carbon-fiber body and neck to keep weight down (yet strength high) while giving you a 20.81" scale length, a baritone size in a smaller package. The result is tenor-like string spacing without excess bulk. Everything points to durability: the gloss-black finish, composite ebony bridge, and Graphtech nut/saddle. We include a padded gig bag made of backpack-grade materials, so your uke is protected on flights or camping trips. Unlike wood instruments, carbon fiber resists temperature and humidity swings, meaning your bass ukulele stays in tune longer and won’t warp or crack in different climates. You’ll find the action impossibly low and smooth (thanks to PLEK precision), with no buzzing. This is perfect for fast fingerstyle or slap, and the neck width (about 1.77" at the nut) gives enough room for bass fingerings without feeling cramped.
Tonally, our Bass Ukulele is surprisingly “booming.” Carbon’s stiffness lets sound travel cleanly through the body, and our Carbon Double Top design (foam core between two carbon soundboards) boosts volume, sustain, and richness. In practice, this means a deep low end and strong projection that can fill a room even acoustically. Reviewers have found its tone “remarkably full and rich for such a compact instrument” with “deep, resonant low end” that holds its own live or in recordings. In short, you get big, warm bass tone from a tiny frame – big tone in a small package. (We’ve even managed to make it sound “woody and warm yet articulate” by carefully engineering the carbon composite.)
As an acoustic-electric ukulele, our Bass Ukulele comes with the KLŌS Bass Uke Pickup – an active piezo system with onboard EQ and a built-in tuner. Plug in, and the uke sounds bright and clear with plenty of low-end warmth. The side-mounted controls let you tweak the volume and EQ on the fly, and the small two-coin-battery module keeps things light. This means you can go straight from jam circle to gig or recording session without adding bulky gear. For players who use it unplugged, the tone is open and balanced; for those who go gigging or recording, the preamp adds power and clarity.
Who benefits from this design? Beginners will appreciate the tenor-scale spacing (easier fingering than tiny sopranos) and the rock-solid tuning in any environment. Experienced players and giggers love the quick setup (it arrives tuned and ready with low action) and the ability to plug in instantly. This is comparable to how Kala positions its Journeyman U•BASS as a stage-ready, affordable bass. Travelers and outdoor musicians will note that our carbon build is truly all-weather; you can compare it to other travel or all-weather ukes (Journey’s carbon travel bass, for instance, is rated -40°F to 250°F). In practice, you’ll carry a virtually indestructible instrument that “is easy to grab and go,” with the confidence that it can take bumps and never needs mid-song tuning. Recording artists get a surprisingly full-range tone for tracking, thanks to both the acoustic body and the onboard electronics.
In price and features, the KLŌS Bass Ukulele sits above entry-level models. For comparison, Kala’s Journeyman U-BASS uses mahogany and sells for a few hundred dollars, and Alvarez’s AU60E Artist Bass has a spruce top with a mahogany body and an onboard EQ (20½" scale) at around $419. Those are fine starter bass ukuleles, but we found players wanted more projection, consistency, and durability. At $1,799, our carbon bass ukulele is an investment. But it delivers exceptional value: lifetime tuning stability, all-conditions playability, and carbon-fiber tone you’d be hard-pressed to find on any wood model.
Whether you’re a hobbyist who wants a travel-friendly bass uke in your camper, a gigging musician needing a reliable plug-in bass, or anyone craving a unique sound, this is our solution. We’ve seen players call it a “serious punch” in a travel-size instrument, and once you play one, you’ll hear why. It’s a bass ukulele built for the road and the stage: low in weight but not in tone. You never have to compromise on performance, no matter where you play.
