So, I've been experimenting with different tunings in my head for months! One of these tunings just won't seem to go away. It's similar to Victor Griffin's drop-B tuning: (low to high) B A D G B E, but it would be on a 5 sting bass, so B A D G C. Is this a practical tuning? Anyone know if it has been used before? How much would that E string be missed?
