The Mounties don't fit on every single pedal made, but they can fit most pedal models. I have a great deal of confidence packing up and transporting my pedalboard knowing that my pedals are fixed in place with sheet metal screws. You don't have to drill into the pedal shell or change your vintage/expensive pedals in any way. Just find a screw on the pedal where you can slip a Mountie under, re-tighten and you're good to go. In most cases, this would be a screw that holds the bottom cover on (typically through a rubber foot). On my GOAT pedals, there are assembly screws on the side of the pedals at the bottom that worked perfectly for this purpose. The Mounties can be easily bent for 90 degree mounting solutions too. They are too inexpensive not to get them for your pedalboard build!
