I use the temple audio boards, and the pedal plates are a sticky mess (although they do stick really really well) and so I don't want to ruin the bottom of some of the nice wahs I have. I also wanted to be able to mount with velcro if i ever swtched away from the temple stuff.
Now, I know this says "mission engineering" but these fit all dunlop normal sized wahs. I've bought 3 of these, mounted to bottom of wahs i like using and then added temple audio plates to them. They isloate the opedal from any metal board (avoiding ground loops) and the supplied screws are top quality.
Really happy with these, so much so I'm going to buy one or two more so i can easily swap wahs from my collection in and out of my boards.
Awesome
