Simply one of the best songs from one of the best Oomph! Albums, nothing more, nothing less. This German band is a jewel when it comes to the groovy riffs and the melodies that get into your brain and refuse to leave it. Ever :) The bass part is not difficult, but since I couldn't find a correct bass tab online I just made my own part which can be quite different from the original one here and there.
P.S. The tuning is standard and yes, I'd say it's better to play it with a 5-string bass.
