I've never used a pedalboard before, and always just left my stomp boxes on the floor. Now I need to keep things clean and neat while I'm singing, and would like to buy a pedalboard that holds about 4 or 5 pedals and a wah in a single row. a few questions: Should I get one that is self powered, or buy the power supply and board seperately? What about cabling between pedals? I really want to keep a nice compact setup for ease of use.
