I don't like any of the methods I've seen for attaching pedals to a pedalboard. I want to modify my pedals by removing the bottom panel, drilling a hole through the center of them and inserting a bolt through the bottom and aligning it with a hole on the metal pedal panel (holeyboard) and then fender washer/wingnut tightening them on the underside. I'll use a thin nut to keep the shallow bolt head tight to the inside of the pedal enclosure base panel so as to not touch internal components on the device. Has anyone ever used this approach? It doesn't seem like it should be a problem in any real way, other than potentially voiding any warranty on them by the modification. Might there be in issue in connecting them through the metal bolts to each other via the panel board metal? I don't see myself adjusting the layout for the few that I have, and if I do a drill will make short order of the process.
