The lined fretless UBASS-RMBL-FL from Kala is an acoustic/electric Rumbler U-Bass fitted with an agathis top, back and sides, a mahogany neck, and a rosewood fingerboard and bridge. It can be used by musicians and students in recording studios, rehearsals, for playing live on stage, and more.

The fretless U-Bass produces the same pitches as a standard bass instrument and is tuned in traditional bass tuning: E-A-D-G. Featuring a 21″ scale length, the Rumbler U-Bass has an active EQ and built-in tuner to provide tone control and spot-on tuning. The rosewood fingerboard on this fretless U-Bass has both lined fret markings and white dot markers at the 3rd, 5th, 7th, 9th, and 12th positions to help identify where the 16 frets would be on the fretted version.

The black die-cast tuners ensure the instrument will stay in tune, and the Graphtech black TUSQ nut and saddle deliver a balanced tone. The Rumbler U-Bass is set up with Aquila Silver Rumbler strings and ships with a padded gig bag.
