I have a DOD FX17 volume/wah I want to put on my Pedaltrain Jr. The problem I have is that the bottom of the pedal has wavy/ribbed rubber so it's not particularly amenable to attaching velcro. Compounding the issue is the fact that it doesn't have any screws on the bottom to do the bike chain trick. Given all that, does anyone have any words of wisdom about how I can attach the pedal to the board? Thanks!
