Bass amp for acoustic band setups

[tinyd]

Pretty much what @Tradfusion says above - I use a Warwick Gnome head (similar to the TC heads) and Phil Jones C2 cab - I play jazz on DB with a drummer, piano and vocals and it's plenty loud enough so you should be fine with your lineup. The total weight is about 10KG so it's an easy carry. As others have said, there may be cases where you need to go louder but in my experience of playing "acoustic-ish" music this is usually done via the PA so you don't need big volume from your own rig.

Some further good suggestions and info, thanks! It's certainly giving me plenty to think about and consider.

Should add that one of these and direct into the PA works pretty well!
