That's it.
However, I did have a problem with the amp at a gig, after the guitarist spilled a pint of Guiness over it. We had it apart, and dried it out with a hairdryer, but it wasn't happy. After that, I always made sure I had an emergency DI arrangement, which was bassically a very long lead directly to the desk/PA, so that I could do a gig without an amp at all if I had to, which I had to do a couple of times. My foldback was via the wedges, and was pretty poor, but I'm told the sound out front was great when I had to do it.
