Bwomp Mushroomhead 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 (guitaretab.com)
