The whole guitar is tuned down one full step, and then the 1st and and 6th strings are tuned down another full step.
So it's double dropped D and then another full step, but you don't need to drop it down that far to sound good.
Neil Young has said he has epilepsy. Yes, epilepsy is a disability, that in some cases can be controlled with medicine, a VNS or through surgery it might be illiminated.
For crying out loud how are the retards gonna try and take credit for Neil young? Fucking epileptic piece of shit. If trying to relate to neil young makes you feel better that's fine but epilepsy is a disability, and I'm not even sure neil has it. Fucking neil is better than everyone, not because of epilepsy but in spite of it
