There are loads of alternative tunings,Joni Mitchell uses over 90 according to a man named Howard Wright, who put them all on the internet a while ago. I once saw Ralph McTell and he had a semi circular rack with about 8 - 10 guitars on, only played 2 or 3 in the whole gig! Saw a guy at Fylde this year he had about 4 National and Dobro guitars with him. There is quite a definative book available called "Alternative guitar tunings" by ? ( I do have the book, it's just not to hand right now! If you want the full title, author iSBN etc I will put it upin the thread. Happy New year all.
