Love the U-Bass!
I'm a bass player who doubles on electric and upright. The U-bass is a great alternative to bringing out the upright when space is at a premium. It does have a upright-ish sound, but it does have it's own thing going on too. It's also a great for travel or just sitting on the couch. I have a friend who's a Nashville cat that uses his on pro level gigs. I fell in love with his and mine is just as awesome. The strings require a little getting used to ( a light touch goes a long way) and do stretch a bit when new and may require rewinding. Very pleased with my purchase and Sweetwater customer service is top notch.
