I want to know how to make the "bouncing" sound that starts at 3:30 in the video here: youtube link

You can't see anything about that guitar sound, unfortunately, due to the video editing.

To me, this is either:
1) some crazy technical guitar trick that I want to learn (hopefully, because then I can learn it)
2) some sort of "cheating" guitar effect that layers on this sound afterwards
3) some kind of custom guitar made just for this sound and not a normal guitar

How is this sound made?
Firstly, great choice. I heard this song recently and have been banging my head to ATB ever since. Great stuff. I wondered the same thing though when I heard it. It sounds like they just have some serious noise gate stuff going on. Not much of an answer but that's my take on it.
