I have square screws in my reed switch boards

 If you have screw heads with square holes in them in your pedalboard reed switches, you can still adjust them.

The screw is a #4 Robertson (square) screw. 

The correct screwdriver to use on it is a #0 (Yellow) Square Screw driver. See it at Home Depot.

Once you have the screwdriver, you can follow the adjustment tutorial.
