all but drop tunings, depends on the style also
7 string: Drop G. G-D-G-C-F-A-D
6 string: Drop G, Drop A#, Drop C
Drop D or drop c or if im playing motley crue some kind F tuning i cant rember what its called guess thats what happens when you get old you keep having senior moment orCRS there both the same.
F standard... or E standard.still deciding
i use a dropped most of the time, mostly C but i use D too.
