I'd suggest bringing along your adaptor and see if the connection is a tight fit with the daisy chain. I have had a problem with the connection point between both, just stepping on it or kicking against caused my amp to go silent. So I got some sanding paper and some ducktape to solve it. Still no good so I made a little plastic box to cover it. Now it's fine, I can litteraly jump on it without having the sound crap out on me.
