If you're talking Jerry's opening riff this is how I see it-
In A
g---5h6--7-5h6---------
d-------------7--
Slight hesitation between the 6 and 7 thus 2 dashes. You can voice the d chord on the 7th fret over the 7 on the g if you like.
A fuller sound would look like this-
-A------------D-----A
e--5--5-5-------------5-
b--5--5-5-----7-------5-
g--------5h6--7--5h6----
d-7---------7-7-7---7---
Jerry played variations on this in a whole bunch of songs.
If this ain't it - clarify and I may be able to help you.
