I am not a carpenter or a professional pedalboard builder. I love recycling things and love working with wood. My pedalboards work well and are cheap, but are certainly not comparable to super professional products.
This board has a power supply connector on the back. You can connect your 9v power supply there. This supplies the two 9V sockets on the top. These each have a potentiometer with which the voltage can be adjusted from 0-9v. Velcro is included
