How are people attaching Line6 ToneCore pedals to their pedalboards? These heavy pedals have a thick rubber backing that covers the entire bottom of the pedal. Do you take it off before putting velcro on? If so, how do you get it off neatly? Or is there a velcro that sticks to the rubber backing? Or is there a non-velcro method that works well and doesn't look bad? This is to go on a Pedaltrain board. All useful suggestions appreciated.
