So like many of you I cover my pedal board when not in use to keep the dust and stuff off it and with that and putting it in and out of it's case to take it places the knobs moving has always frustrated me. That stomp lock thing that digitech has with their hardwire line really cool and I love it. I've been toying around with the idea of retaining straps, foam sheets with cutouts, etc to try to come up with my own and I think I finally found something I like. I found some little round sticky back velcro dots and an old rubbermaid container and used them to make my own. Now it's not as solid as the stomp lock but it does prevent the the knobs from turning unless you actually reach down and turn them. It comes off easy, goes on easy, and doesn't really get in the way. So you just cut out a piece of the rubbermaid to make a shape that covers the knobs, stick a little velcro on the top of each of the knobs, attach the mating velcro to the top of the knobs so the sticky side is sticking up, and then just press the rubbermaid cutout on top of it. So far it is working out but it is a fairly new thing for me to try.
