About the Kala U-Bass Solid Body

Kala's U-Bass concept fits a genuine 4-string bass guitar - full EADG tuning, a split-coil pickup, volume and tone controls - into a body barely bigger than a baritone ukulele, achieved through a short 23.5-inch scale and thick, low-tension rubber/nylon-core strings rather than steel roundwounds. Those strings are what give the U-Bass its distinctive round, upright-bass-adjacent tone despite the small body, at a fraction of an upright bass's size and weight.

The Solid Body variant uses an okoume top and body with a maple neck and laurel fingerboard across 22 frets, finished in gloss with matching black hardware: a top-loaded 4-saddle bridge, closed-gear bass tuners at an 18:1 ratio, and a passive split-coil pickup wired to simple volume and tone knobs. A spoke-wheel truss rod allows standard neck relief adjustment, unusual on such a short-scale instrument.

Sound character of the Kala U-Bass Solid Body

The thick rubber/nylon-core strings under low tension are the main reason this sounds nothing like a normal bass guitar: they damp high-frequency overtones and produce a round, upright-bass-like fundamental rather than the bright zing of steel roundwounds. The passive split-coil pickup keeps the signal simple and warm, without the added edge active electronics would add.

The history of the Kala U-Bass Solid Body

Kala popularized the U-Bass concept in the late 2000s specifically to give bassists (and ukulele/guitar players wanting a portable bass) an instrument that could travel easily and be picked up without amp-stack volume, while still producing a genuinely deep, upright-toned low end through its specialized strings.
