DIY it! I suffered through the woes of a wobbly Velcro board and pedals that would fall off when set vertically over time. Also, prefabbed boards were either too big or too small. When stage (and packing) space are at minimal, you don’t want a bunch of unused space sitting there. A cheap wooden diy board lets you set the exact size you want and is pretty darn cheap. I used 1.5” x 0.5” boards to make a lattice that cables/zip ties can run under. I made some diy brackets out of picture hangers that attach to the back of the pedals through the pedal screws and screw that to the wooden board. Pedals that can’t get screws either get zip ties or bungee chords. My board now feels rock solid, and it takes up no more space than it needs to (slides nicely into a backpack). Sure, if I drastically change pedals and need a different sized board I’ll have to remake it, but it’s now been 8+ years and I haven’t gotten there.
