Almost Magic

For a single, cheap power source, this manages to power my pedalboard using daisy chains alone with minimal interference. I plan to use this until my board gets complicated enough to upgrade, but it's really the only option needed more a starter/basic board.

Solid starter choice

When buying your first pedal, this is a solid choice to power it. Otherwise, there are better options, and using this with a daisy chain can cause damages and/or unwanted noise on bigger pedalboards
