Ronnie McCoury used GG DD GG BD for "Black Mountain Rag" with Doc Watson in the Key of G. My jam partners don't care for this key for this tune, but my wife loves it, so if I ever get a decent #2 mando, I'm going to keep one tuned like this just for BMR.
Didn't have the Eastman when I wrote this. The Kentucky is now tuned GG DD GG BD
