Here we have the Showman board, which is 750 x 350mm (internal) - large enough for all the pedals you can see in the picture.  Diago does one bigger and two smaller boards, all of which are made from half-inch plywood and covered with tough black 'polyweave' cloth.  Add sturdy plastic corner protectors and decent catches and handles, and this is one protective box that you can abuse without worry.

Inside, the base is covered with Velcro, and there's a three-metre roll of Velcro tape to attach to the underside of your pedals.  It's a simple, straightforward solution to the nightmare of organising your stompers, bereft of any flashy angled or variable-height sections of other manufacturers.  Our one criticism would be that repeated reorganisation may cause the Velcro base to wear in time and perhaps lose some of its grip.  Other than that it's a dependable board.
