This Kala U-BASS Review looks at the UBASS-SB-TB-FS Tobacco Burst Solid Body Fretted UBASS. Kala takes the compact UBASS concept and pushes it much closer to a traditional electric bass, complete with metal strings, magnetic pickups, and standard E-A-D-G tuning. Although UBASS instruments have always been known for their small size, this model feels different. Instead of leaning heavily into its ukulele roots, it offers many of the features bass players already know while keeping the portable dimensions that make the UBASS so unique.
Classic Electric Bass Style in a Smaller Body
The first thing that stands out is the offset solid body shape. Rather than using a traditional ukulele body, Kala gives this model the appearance of a compact electric bass. Meanwhile, the Tobacco Burst gloss finish gives it a vintage look that works especially well with the white pickguard.
Kala uses okoume for the body, while the neck is maple with a laurel fingerboard. Mother-of-pearl fingerboard inlays add a more polished touch. In addition, black hardware throughout the instrument contrasts nicely against the burst finish and white pickguard. The entire instrument measures only 33.25 inches long and weighs about 5.5 pounds. Therefore, it is considerably easier to carry and handle than many full-size basses without feeling like a novelty instrument.
The 23.5-Inch Scale Changes Everything
One of the biggest reasons to consider this UBASS is its 23.5-inch scale length. Compared with a standard electric bass, the frets sit much closer together. As a result, long stretches become easier and moving around the fretboard can feel considerably more relaxed. However, Kala still gives you 22 frets, so the shorter scale does not mean sacrificing much playing range. The compact dimensions may appeal to newer bassists, traveling musicians, guitarists moving into bass, or experienced players who simply prefer a smaller instrument.
The shorter reach can also be useful for players who find a traditional bass tiring over longer sessions. Instead of fighting a long neck and wide fret spacing, you can focus more on groove, timing, and technique.
Split-Coil Pickup and Traditional Bass Controls
Kala gives the solid body UBASS a passive split-coil pickup that immediately makes the instrument look and behave more like a familiar electric bass. The pickup sits beneath the strings in a layout similar to what many players have seen on classic P-style basses. Controls stay refreshingly simple. You get one volume knob and one tone knob, so there is very little standing between you and a usable sound. Turn the tone up for more definition and attack, or roll it back when you want something smoother and warmer.
During the review, the bass was played through a Blackstar Acoustic Core amplifier. Even through a relatively straightforward setup, the split-coil pickup delivered the crisp attack and solid low-end character you would expect from an electric bass.
Roundwound Strings Give It a Different UBASS Feel
Traditional UBASS models are often associated with thick rubber-style strings. However, the UBASS-SB-TB-FS uses Kala roundwound metal strings. That change makes the playing experience feel much closer to a conventional electric bass.
The strings provide a firmer feel under the fingers and a more familiar attack. Consequently, bass players moving to this model will likely find the transition more natural than they would on a rubber-string UBASS.

The tuning is also completely standard. You get E-A-D-G from lowest to highest, just like a traditional four-string bass. Therefore, the notes, scales, patterns, and bass lines you already know transfer directly to the instrument.
Bass Hardware Without the Full-Size Bulk
Kala equips this model with a top-loaded four-saddle bridge, allowing each string to have its own saddle. Meanwhile, black closed-gear bass tuners with an 18:1 ratio provide the familiar tuning hardware expected from an electric bass.
A spoke-wheel truss rod makes neck adjustments more accessible, while two black strap buttons allow the bass to be played comfortably while standing. Together, these details make the instrument feel purpose-built rather than simply being a ukulele modified to cover bass frequencies.

Who Is the Kala Solid Body UBASS For?
The most obvious audience is the bassist who wants something smaller without giving up the familiar feel of an electric instrument. Because it uses conventional tuning, frets, metal strings, and magnetic pickups, there is very little adjustment required when moving from a standard bass.
It could also be a great fit for guitarists who want to add bass to their playing. The shorter scale feels less intimidating than a full-size bass, while the traditional string feel makes it more familiar than some other compact bass designs.
Meanwhile, experienced players may appreciate it as a travel bass, practice instrument, or simply an alternative for situations where a full-size bass feels unnecessary. Its smaller dimensions make it convenient, yet it still delivers the essential experience of playing a real electric bass.
Final Thoughts
The Kala UBASS-SB-TB-FS Tobacco Burst Solid Body Fretted UBASS takes the compact bass idea in a more traditional electric direction. With its 23.5-inch scale, roundwound strings, split-coil pickup, and familiar E-A-D-G tuning, it feels surprisingly natural despite its size.
Ultimately, that may be its biggest strength. You get something portable and comfortable without having to completely change the way you play. For bassists who want a smaller instrument that still looks, feels, and responds like an electric bass, this UBASS makes a compelling case.
