For the Kala U-BASS player, Kala offers additional visual options and adds a mid-range punch with the solid spruce top U-BASS with mahogany back and sides. Since 2008, the U-BASS is still grabbing ears and turning heads. Praised for its colossal low end, the acoustic-electric U-BASS features a new custom-designed shadow pickup system to dial in sonic boom. Includes gig bag.
