For the Kala U-BASS player, Kala offers a Hutch Hutchinson model that 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.
