History of the U•BASS®

Kala Celebrates 15 Years of U•BASS®

The Kala U•BASS®, the original short scale bass, was designed by Owen Holt from San Jose, California. Owen and Kala founder Mike Upton formed a friendship in 2007 and together brought the Kala U•BASS® to the masses in 2009. Known for its immense low end, the compact U•BASS® packs a thunderous punch and is suited for any genre of music or style of play. The portable U•BASS® makes a great addition to any bassist’s arsenal. 

With the evolution of both the player and the instrument, Kala strives for an equal balance between innovation and tradition in support of your musical journey. Fifteen years after the introduction of the original U•BASS® marks a year of both celebration and reflection for this wonderful and unique instrument—read on to see what's coming for 2024!
