I'm building a pedal board, and I don't know the DC input for effects pedals. I'm assuming 9 volts, considering they are powered by 9 volt batteries. I bought one from Radio Shack, but it doesn't work for any of my pedals. It's input is AC: 120V 60Hz 7W and it's output is DC: 9V 350mA It fits the pedal, but doesn't power it up. This is with the battery in or out. I don't have the maunal for the pedals anymore, if I ever had them to begin with. Or is there something better to use, other than a bunch of AC adapters and a power strip?
