This is Feuer Frei (Open Fire / Fire At Will) by Rammstein off the album Mutter (Mother)
I don't know what the other fools were listening too when writing their tabs so I 
figured I'd tab out the correct version.
Tunned to Dropped D low to high D-A-D-G-B-E

e|---------------------------|
B|---------------------------|
G|--------let ring-----------|
D|-5-------------------------|
A|-5-------------------------|
D|-5-------------------------|

With light Wah, slowly dipping the pedal as you repeat the riff.
Also try to slighty pinch the notes like a pinch harmonic if you know how.

The second keyboard, tabbed out for guitar, so you not standing there looking
