Does anyone have experience with using full fifths tuning on a 12 string? Ex: beE eaA adD dgG Any advice on what gauges to use for the fifth up strings using a D'Addario 12 string set for reference? I'm thinking it will work to go to the next lightest gauge octave string and tune up slightly. I probably won't end up doing this on a full set if I do it, just planning ahead so I don't end up buying a bunch of 12 string sets and singles. Makes my checking account cramp up just thinking about it.
