Re: best way to permanently attach pedals
Don't stick on the Velcro!!! The sticky stuff just doesn't work.
All you have to do is take and cut four squares of regular Velcro; they can vary from 1/2" to 3/4" to 1" squares depending on how much hold you need or how heavy the pedal is. Remove the screws from the bottom of your pedals. Take a small awl (I used the one on my Swiss Army knife) and punch a small hole in the center of each Velcro patch. Insert the screw into the Velcro (it should be hard to get the screw through the Velcro) and then put the screws back into the pedals. Et voila! If the hole is too large, it might pull through and not hold; if you need to, you can use a small washer to increase the size of the pressure area under the screw.
I use small strips of Velcro to tack down my cables, keeping the routing nice and neat. I have been doing this since about 1980 and I have NEVER had a pedal come off a board, even when I was using just an old piece of 9-ply birch shelving and no case to carry it in. I've upgraded a few years ago to the Furman SPB-8 with the carry bag, and again, no issues at all. And I can get the pedals off the board when I want to, without pulling any muscles--too much Velcro is not necessarily a good thing. LOL!
I know there are lots of other ways to do it, but this system works well for me. Good Luck!
