Nice Zack. You're right. With two players doing that, you can make some creepy music that would fit as background to a horror movie. Especially if you get some reverb or delay going on them.
Spior, those are the 6 strings from left to right, EADGBE. X represents a string that is not played or is muted. Each number corresponds with a fret number. Those are pretty much standard bar chords.
