Anything lower than B is not even music.
Even he uses a custom SEVEN string, which is absolutely awesome...

I hope they make a six string version...
Whoah!!! It's got fanned frets as well!!!
He must have super light strings on there, look how far he's bending the E string ( I think that guitar's 8th string is higher, not lower... )
