Kala Rumbler U-Bass Fretted Acoustic Electric Portable Bass Ukulele.
The Kala U-BASS is truly a ground breaking short scale bass that produces the same pitches as a standard bass instrument and is tuned in traditional bass tuning, E-A-D-G. The U-BASS is strung with proprietary strings that incorporate a great bass feel with balanced tension. The U-BASS is a true pleasure to play, and the tone that these instruments produce is amazing.
The Rumbler takes the U-BASS into a new dimension with the addition of custom engineered electronics and new proprietary strings, at an economically friendly price. The Rumbler design integrates a specially designed Kala electronic system with a Piezo pickup and is equipped with an active EQ with built in tuner. Each bass is strung with Kala Silver Rumbler Strings which are proprietary U-BASS strings designed and manufactured exclusively for Kala Brand Music by Aquila strings.
