Who is the greatest philosopher ever?
It turns out to be Keef -- whose picture hangs on my wall, compleat (as they say there in that Newish York) with black Gibson 335 in hand and Louis Vuitton case at his side.

Tramp.

But he said two great things:

"Art? It's just short for Arthur".
"Original Sin? If I knew what that was, I'd go out and do it".

Check out "Downtown Suzie", the first Stones track in straight (aka "slack") G-tuning: DGDGBD -- though Keef tended not to even bother with the bottom D; and you can even replace it with another G.
(Written, BTW, by Bill Wyman.)
It made KR's career, especially if you add the extra bits into the chord -- like the standard Am7 shape.
But I think it came from Ry Cooder.
Was that the basis of the unresolved plagiarism case?

Sledge (or possibly Crispin in emulation mode).
Take your pick.
A Jim Dunlop .88mm will do it.
