I have owned 2: a five-string Ibanez ABG305, with a 32" scale. I put LaBella tapewounds on it, and it had a decent sound, but only amplified. I gigged with a folkie band back then, and bought it mostly for the look of an acoustic instrument (we had fiddles and banjos and mandolins and whatnot). I traded it off because, apart from that look, it wasn't a very satisfactory bass. Later I found a used Martin B-1, which I tried to use for a strictly acoustic group outdoors (one guitar, tambourine, and me) and after a song I hung it up and played my Dobro instead. Just not enough there. It was OK amplified, but my Precisions sound so much better.
Get a small amp. Most of them are unsatisfactory, too, but you might find one that works in the context of your group. I've tried the Pignose Hog 30 and a Ibanez, and both were lacking in real bottom and in flexibility. My Genz-Benz Shuttle 3.0-10t is pretty good, but they are a bit on the pricey side. Good luck.
