U•Bass® Timeline
Since Kala first launched the original short scale U•Bass back in 2009 it has taken the music world by storm. The immense, upright bass sound coming out of the compact U•Bass turned heads and found a community of like-minded enthusiasts. Today there are blogs and lessons dedicated to the U•Bass, with more resources popping up everyday. We are always testing and updating the U•Bass design to ensure that players get a consistently playable instrument that sounds and looks great. Whether it’s developing new strings or a making a cosmetic adjustment like moving the fret markers to make them more visible, we strive to make your experience the best it can be with every U•Bass.
