After I put my Behringer pedal inside the acoustic stompbox, I still needed to drill a hole for the power supply plug.
When I attached the pedal inside with velcro, the box wouldn’t close. So i took the footswitch off. Then I couldn’t turn it off and on, so I used some scrap velcro to attach a leftover Ikea pencil inside.
Now I can plug it in, turn it on with the pencil, close it, use it, unplug it, put the power supply inside, and go.
