I was thinking of making a blues box out of my twelve string guitar; since it's a modern dreadnaught I don't expect a perfect tone, but I think something nice may come out.
My idea was to put on medium strings and tune it two tones down, like Leadbelly did, but there are some questions open: is .13 the only suitable gauge, or I should try others? Do you know of notable musicians who used completely different settings? Do I have to increase brutally the action? What kind of strings should I use, bronze, phosphor bronze or nickel? Is the thing possible at all?
