There's been quite a bit of discussion on here about Mushroomhead's tuning.
Nowadays, they do indeed play 7 strings, but back in the 90's they played 6
strings, tuned almost halfway between two notes. I believe it is almost
halfway between B and C standard, slightly closer to C. Although it is very
possible that they are tuned halfway between B and B flat, or between B flat
and A, and just happen to not play the low notes very much. To my ear, this
tab sounds correct for this tuning.
This beginning part is played on keyboard, but if you happen to feel like
playing it on guitar, here's the main part of it...
