This is the fretless version of Kala's solid mahogany electro acoustic uBass, the uBass 1.  The body is constructed from solid mahogany, giving this really cool bass a rich, woody tone. It is really innovative, with a compensated bridge, built in tuner, active Shadow pickup and a 20 inch scale. The polyurethane strings are an improvement on early uBass models, with more tension now available.

This bass is all solid mahogany, with built in tuner, volume and tone controls. String changes are eased with the addition of a rear panel which is removable.

There's a reason why the UBASS has endured, despite everyone copying Kala's ideas with their own models, it is good quality, with a great, rolling tone and stands up against its competitors.
