With the pickguard free but still in it's original position, pull the knobs off of the pots. This can be done by simply pulling them directly up from the body.

If the knobs do not come off easy, use only a soft pliable material, such as a plastic bag, cloth, or piece of cardboard to wedge underneath the knob. Wrap the piece around the knob and you will be able to get a better grip of the knob and you will be less likely to break the pot.

Remove the plastic top of the selector switch by pulling it directly up from the body, just like the knobs.
