Okay, yeah, lotta stuff is in E but lotta stuff in A or G or D.... C tunin's is "C"hick tunings... Might of fact I had never palying no open C stuff until I got into a battle of the bluesmen and it was 'bout 2 o'clock in the mornin' an' iot was between me and one of the instructors and he borrowed my Stell bodied reso and stuck it in open C... He was trying to mess me up... Well open C is like E but everything just kinda does a shift and so I did "Rollin' and Tumblin" in C...

But now, JS, you go on over to Tweeds and check out the thread about my new CD and if you pay attention and read it real good yer gonna get turned on to the baddest open tuning I have ever come onto which I learnt from listening night aferr night to a 1949 recording by John Lee Hooker...

BTW, you barely scratched the surface here, my frined... Wait until you hear Mississippi Fred McDowell and RL Burnside and Lightnin' Hopkins and Blind Lemon, etc....
