Why not just carry a decent bass DI, so if any or all of your amps go down, you can go through the PA? Not ideal for onstage sound purposes, but a quick fix - and cheaper and lighter than lugging extra amps around.

I used to agree with this but with new small heads not much bigger than a di box yet still equipped with one anyone if you are already going into the desk will give you power to your cabs, a used gk200 won't cost much and will fit in your gigbag, also good for practice rooms with ok cabs but crap heads.
