The Kala UBASS-RMBL-FS isn't called the Rumbler for no good reason. Crafted mainly out of mahogany, this bold little electro-acoustic bass ukulele slings extra-deep and warm sound. It's also been equipped with a Fishman U-Bass preamp system which features a built-in tuner and EQ controls for perfectly tweaked amplified sound, and Kala have appropriately finished this quality bass uke with a set of custom black die-cast machine heads, a Graph Tech TUSQ nut and saddle, and a handsome soundhole rosette and binding. The Kala U-Bass Rumbler Mahogany comes including a padded gig bag.
