I have just read an interview with Page where he explains how exactly he plays
the riff in "Whole lotta love".
The tablature in the archive is fine, but the original sounds a little different.
Here we go:
E--------------|--------------
B--------------|--------------
G--------------|--------------
D----0---0-----|-------------- } and repeate.
A----5~--5~-7--|-7-7-7---7-7-7
E--7---7----0--| 0-0-0---0-0-0

~ stands for slight bend, which is the trick here. D sounds on two strings
simultaniousely.
