I would love to give vital parts of our Orchestras teacher's anatomy for Road show power. Sorry I'm still bitter over some other things. I want to know who has it in there space, how many amps, and what manufacturer of box. I've seen different ones, just looking for the safest and ease of use, Like cam locks instead of old fashion tying in pigtails or hubbel connectors. I'm also interested in what people have to say about company switches. Do you Charge people fees to use the extra power?
