All my pedal board effects are run on adapters.. I use 2 double A's in my wireless transmitter and one 9 volt in the gizmo that makes my guitar smoke.. I have 2 fresh backup double A's for the transmitter, but have never had to use them as I put in new batteries after soundcheck..

I think that's all the batteries I use lol.. Everything is adaptor-run..
