Extremely Portable Acoustic-electric Bass

Kala brings you the Rumbler U-Bass acoustic-electric bass ukulele, so you can have the surprisingly deep, full bass tones of the U-Bass at a value-packed price. Custom electronics and special strings give the Rumbler U-Bass a voice much bigger than its pint-sized body would suggest. It has a piezo pickup, an active EQ, and a built-in tuner, so you'll always sound good. Special strings made by Aquila, exclusively for Kala, make this bass sound rich when played acoustically. But plug the Kala Rumbler U-Bass into your amp and you're in for a very sweet surprise.

Custom Kala electronics with active EQ make this U-Bass a real live performer

Introduced on the 2013 edition of the U-Bass, Kala's custom electronics give this Rumbler U-Bass a vibrant and punchy sound when you play plugged in. An active equalizer lets you tweak your tone, effortlessly meeting the needs of even the most demanding venues. What's more, Kala even equipped this U-Bass with an onboard tuner, which is an essential part of any musician's live kit.

Custom Kala electronics with active EQ make this U-Bass a real live performer

The secret behind the big sound of the Kala U-Bass is almost as cool as its small, ultra-portable format. It comes from the combination of the right tonewoods and Kala's unique polyurethane strings. These lightweight, large-diameter strings provide plenty of low-frequency oomph, which resonates with a deep, rich, and wooden quality that's reminiscent of the coveted upright sound yet colored with a uniquely musical U-Bass quality all its own.

Kala Rumbler U-Bass Acoustic-electric Bass Ukulele Features:

  • A fun and massive-sounding acoustic-electric bass guitar that you can take anywhere
  • Compact 21"-scale, 16-fret fingerboard provides plenty of room to play
  • Fat, proprietary polymer strings, custom-made by Aquila Corde of Italy, deliver deep bass resonance
  • Laminate mahogany back, sides, and top provide warm and woody undertones with a balanced midrange
  • Separate compensated saddles for each string and die-cast tuners keep your tuning and intonation solid
  • Onboard piezo pickup with active equalizer provides exceptional sound in any live environment
  • Extremely portable (meets most carry-on standards)
  • Deluxe custom U-Bass padded gig bag included

Small Scale

I like this little bass. It has a big sound when plugged in. It is portable and I can take it with me to practice away from home. It takes a little getting used to because it is smaller scale. It has a unique sound.
Music background: Bass player 5 years.

Amazing tone in a small package

Plugged this beauty and couldn't believe the sound I was hearing: rich deep bass with an upright reminiscense and clear well defined notes. You have to get used to the strings feeling and the action, but once you are there it's a pleasure to play.

Original strings were ok, but a bit sticky. Put a set of Aquila Thundergut on it and tone and feeling improoved a lot.

I use it throug a Markbass rig with a CMD 121P Combo and a Standard 151HR and the tone is just amazing.

As a plus it is really easy to carry with the supplied soft bag, specially when you travel a lot like me and could check it as a carry on baggage.
