Be aware that almost all acoustic basses need to be amplified. They don't put out much volume otherwise - basic physics is the reason the upright bass is so large - and are really only good for living room practice when unplugged. You cannot hear them jamming even with one or two other acoustic players, with only a couple of exceptions (Tacoma Thuderchief, long out of production).
It's a little off the beaten path, but I like my
Kala U-bass ukulele. Plugged in it sounds very much like an upright bass. In fact mine was on stage about 90 minutes after buying it. After our set, someone came up to stage side and said, "I could hear the bass, but didn't see it on stage anywhere". I just handed him my U-bass and watched his jaw drop.
