Sure, go for it!
In the description below you can see where those lugs go.
Lug 1 goes to ground (any ground) and Volume 2 goes to output (this is the postion on the switch for output, not the output jack).
The bottom looks like it has some potential bridges though:
I could be wrong, but I would go through them with a knife or something to make sure the tracks are clear.
And if you have any doubts, just come back with new questions :)
