Hello all , I like to keep three guitars on stage. I have a 018 martin that is my most used instroment{If I have to take just one, thats the one} <<>>> I have a Kay Profestional that I will put in D tuning and the Diolian National I put in G...How many guitars did Eric Clapton take on his Cradle the Blues tour????? I wish !!!! Oh there is one Martin Carthy song "My Geordie" that I think he did in G tuning but with a dropped C note on the sixth string.Also "Shepard Oh Shepard" must have been done in G tunning { I think???}
