Nice, thank you for sharing. I got tired of "chasing" my pedals all around my hardwood floor and gave up, so I bought a dual Boss FS6 and put it against the wall. The ergonomics aren't good, it's a litte too far away. But at least now it can't move further away after multiple presses! Definitely need to do something like this myself!!
I rather use my 2 FS5U pedals linked vs the FS6
which I didn't like due to the battery it had to have.
