Thank you for the reply Axldeziak. I've had not so good experiences with sticky tape or super glued velcro where it comes off if ever I take out the pedal. I always move pedals from two pedalboards, a small one (3-4 pedals) and big one (8-10 pedals).
I guess there's no other option huh? Do I need to sand the bottom of the can so the tape/superglue will stick? It won't stick well on shiny surfaces, right? I've always attached velcro on the enclosure screws every since I stopped tape/gluing them.
