Mounting these to a wah pedal, there's no supplied screws, using the screws from the wah, the holes are too big, and the screws will break/split the wood. So it gets a 1 star for the mounting. Simply adding a screw set cmpatible with dunlop or other wahs, and some washers to protect the wood would make this a much much much better product. As it stands, I had ordered 3 sets, and all of them have gone in the bin.
Once you do have them mounted (somehow) and put on board, removing from board, the velcro sticks really well, to the point that if you get it off, the screws will most likely split the wood, and these plates will still be on your board, and the wah in your hands, so effectively they last one, maybe 2 board removals before they're dead.
Waste of money. If you want a solution for mounting a wah on a pedalboard, go look at the mission engineering mounting kit instead as these are not worth it.
Only positive is that the velcro sticks really well.
