I think Black Stone Cherry tune down like this. The guitars play their bar chords as 555 or 666. There is no 355 for a G chord. Personally, I have a 5 string and tune down a 1/2 step and was very reluctant. Since the rest of the band does it made it easier to transpose, but still, my B, now A# is boarderline flapping.I tune down my basses this way:
E > C#
A > F#
D > C#
G > F#
Does anybody else of you do so, too?
