With the free velcro that came with the Westy bag , i used em on my DD20 but after 2 months , the gluey part couldn't stick strongly and now it does slide off a lil , leaving some residue on the interiors of the bag.
i pasted the industrial velcro on my pedal's rubber part and stuck it on my pedaboard then when i wanted to shift it's position, the whole rubber part came out. -_-
