OK...there is a power bar on the left hand side of the board that runs vertical. On the bottom of this power bar there are 4 holes for set screws..so thats how the bar stays on. I then have 3 seperate power supplies (2 BOSS and 1 DUNLOP)..the DUNLOP goes out to the wah because it is seperate from the board. 1 BOSS goes to an Ibanez daisy chain power cable which goes to 5 pedals. One pedal uses a battery because I bought it second hand and the first owner broke off the power supply inside. And the Last power supply goes to one pedal, however I will be getting the Ibanez daisy chain because I will soon be getting the EH Reverb to slap on.

Yes, all pedals are held on by velcro.
