Personally I think everyone should have two guitars one for standard tuning and one for Drop D....my boyfriend unfortunatly disagrees with this theory...he doesn't play.
not to out do you, but here is an extended list (I got to thinking "didn't zeppelin have one or two of those?", and in looking I quickly came across this.
http://www.ultimate-guitar.com/forum/archi...p/t-218247.htmlI think everybody should have 9 guitars, and several of them should be in alternate tunings. when I took up guitar again (after many years) i thought "well, I know I will want these, and I can either spend the next two years obsessing over if I am getting them, or I can just quickly get it over with and save time" 5 gibsons and two fenders. I kept my martin and dobro from the dark ages (the martin lifetime warranty is great, after that many years any guitar is going t need luthier work, and martin will pay for most of it). Problem is it takes 8 months to get somebody decent to work on it.
But to the point, alternate tunings are great, primarily they give you ways to use open strings. and of course for slide. one tuning I have been interested in is lute tuning. never played with it, but I think it would be more suitable for minor scale stuff. the difference is that the second string gets tuned up a semi tone, and the 3rd down a semitone. maybe I will set my dobro to that. everyone should have a dobro, they really sound cool, not just for slide.
