It's a board I made out of hardwood flooring scraps. It's a bit like a pallet in design. It has the 3 main pieces and the slats on top are screwed into them. The pedals are velcroed to the slats and the 5 amp power supply is velcroed underneath with a 1-in-8 out adapter. EDIT It makes them easy to move around. Throw in the car, put on top of the amp. Connect to the amp, disconnect from the amp. It's just convenient.
