I have a Dean acoustic/electric 4-string bass I played for several years in an acoustic rock trio. I used D'Addario Acoustic Bass Phosphor Bronze strings. They sounded and played quite nice.
A word of warning, though; Don't be surprised if you find the overall volume of the instrument to be underwhelming. They are generally fine by themselves. However, my experience has been that they get swamped in the presence of two acoustic guitars. Mine was fine in a PA at gigs, but at rehearsals in one of the guitar players' living room it was just lost.
I still have mine hanging on the wall in my studio, but haven't played it in several years. I keep waffling back and forth over keeping it or selling it. I always seem to convince myself that I'll want it for something as soon as I sell it, though. So for now, it remains.
