As a newbie, I'm wanting to know the following.
When changing from Double C tuning to the key of D (or from open G to key of A), do you tune to C (or G), and then use a capo at 2nd fret and for the 5th string use the railroad spike 2 frets above the open position?
Or do you just tune up -- tighten all strings to raise overall tuning to one tone higher?
I'm wondering about the effect on the tone of the either method, as well as the structural safety of the increasing the tension of the strings associated with tuning up a full tone across the board.
