I bolt my pedals down to my board instead of Velcro. I find this to work pretty cool since almost losing a pedal or two to drunk idiots over the years. It doesn't modify or hurt anything on the pedal, and is super secure. I guess the only neg is having holes in your board and if you change things around allot. For those not picturing what I'm doing... Get extra long same thread screws and use the bottom cover of the pedal as a template, drill holes, and then run the longer screws up through the bottom of the board into the pedal. It's been easy to find longer screws for most pedals at the local hardware store... Except, my D13 Switchazel, (and it's a huge box that Id really like bolted down). I'm guessing the box is foreign, and the screws seem to be a metric 3.5mm. (Definitely not 3 or 4mm. I tried those and its in the middle... US doesn't work either). Does anyone know where I can find a 3.5mm thread screw about 1/2" long for this thing? It appears to be rare (I've done some searching). Makes me wonder how they had such a supply to stick them in there to begin with. Help is greatly appreciated! Thanks.
