Have loved playing my acoustic-electric Kala U•Bass for a couple of years now, and the warm, dark tone of it is perfect for a lot of stuff I do, but there are times when I want a more typical electric bass/roundwound string sound. Have been waiting for the new solid body U•Basses to come out, and jumped on this when they did. It was just what I was hoping for. Quite playable straight out of the box -- haven't even bothered to tweak the setup in the couple of weeks I've had it so far. No issues I've noticed with components or build quality. Sounds great through either my old Ampeg BA112 or my Phil Jones Bass Nanobass X4. I'm not sure you can fit more fun into a smaller package than either U•Bass with the X4.
