| 'These Walls' by Dream Theater is a six string baritone in A, so that would work well in that tuning.
The whole of Death, Symphony X, and Paradise Lost's back catalogues are in D standard (although I'm not sure whether Greg still tunes down a tone on his sevens).
I think most Motley Crue songs (at least the early ones) are in D standard.
Actually, it's suprisingly hard for me to think of bands who aren't Korn who tune to A on sevens. It's much easier to think of bands who tune to Bb... |
