Have the following tools ready

Micro flat head screwdriver for knobs.
Flat head screwdriver.
10mm socket driver for pots.
11mm socket driver for jack.
14mm socket driver for bypass switch.

Use the micro screwdriver to remove the knobs.

Remove nuts from all pots, jacks and the bypass switch.

Use the flat head screwdriver as a pry-bar to free the input and output jacks from protruding through the holes in the case. 

Pressure should be applied to bend the case, and not the jacks or circuit board. 

The video below may be helpful.

Once the jacks are unseated from the case push the pot shafts and bypass switch against a flat surface. The circuit board should pop out without applying extreme force.
