If you listen to Born Of Osiris, you surely know that they use 7 string guitars in most of their songs. Well, i'm listening to "Tomorrow we Die Alive" right now (for the fifth time).
I know that "Machine", "Divergency" and "Absolution" are in Drop C on a 6-string guitar, and "Exhilarate" is on a 7-string (tuned to drop G). Anyone knows if "Mindful", "Imaginary Condition", "The Origin", "Aeon III", "Vengeance, "Illusionist" and "Source Field" are on a 7-string or on a 6-string?
