The Kala Rumbler was designed to be "just right". It sits between the more inexpensive U•BASS and higher-end models. Created to be its own thing, it comes with custom Silver Rumbler polyurethane strings, a sturdy build, simple appointments, and is still heavy on the low end. Great for recording, playing in an ensemble, or on stage - the Rumbler includes a Shadow® pickup and EQ with a built-in tuner and custom Deluxe Padded Gig Bag. Available in a Fretted and Fretless Model.
