Visual Sound 1 Spot 5-plug "daisy chain" for powering more than one effect pedal with the same power source. You need the 1 Spot power supply first for this to work! Without it, you have no power to work with. This great connector eliminates the need for batteries or other power plugs. Simply plug your 1 Spot into this daisy chain, and it will power up to 5 pedals. You don't have to have 5 pedals for this to work; add pedals as you need them. It's that easy. Great product for any guitar or bass player using pedals or effects!
