Made mine from mdf an cable ties, realy not that difficult, for just a "board" an thats all it realy is you can custom make it it to exactly how you want it , drill a couple of holes eith side of the pedal an hold it down with a cable tie (holds it better than velcro an doesnt mark the pedal in anyway), cover the board in carpet tape (looks better than bare wood an helps with grip), looked at loads of boards like pedaltrain etc an cant justify the cost for what thay are, (the post above looks even easyer, no drilling needed)
good luck an all the best Dan.
