I think Dave plays it mostly on A D and G, so the main riff, for example, would be like this:

E|-----------------------------------------|
B|-----------------------------------------|
G|-4-4-4--X--7--X--4--X--3-3-3-3--X--7--9--|
D|-4-4-4--X--7--X--4--X--3-3-3-3--X--7--9--|
A|-2-2-2--X--5--X--2--X--1-1-1-1--X--5--7--|
E|-----------------------------------------|




***BTW, where it says 'X' it could actually be open***

Dave (guitarist of engerica) told me the real way to play it is that \"the verses
and main riff is just played as
octaves on the A and G string and on the last time of the 1st and 2nd chorus
it goes B5, E5, F#5 and then A5, Bb5 and then up to that verse riff again
apart from on the end of the 1st verse where it goes B5, E5 G5 and ends on
Bb5\"
