LED ZEPPELIN - "ramble on" Tablature

If you care, here is a transcription for Led Zeppelin's Ramble On
(Note: I am doing this without my bass so there may be a couple mistakes;
Listen to the recording for the timing.
G 7/11 11/9 | 7/13 13/11 11/9 | 6 9 6 :|
D 9 7 11| 11 9| 7 9 9 :|
A 7 | 7 | :|
E | | :|
^this is the verse. Watch for variations, as Jones sometimes omits the D
flat at the end of the 1st phrase
G | |
D | |
A 6 77 76 | 6 77 76 |
E 0 2 4 5 7 7 |0 2 4 5 7 7|
^this is the pre-chorus - be careful, the timing is tricky
G
D 9 14 12 12 13 14
A 7 7 7 12 12 12 12 12 12 12
E 0 2 4
^this takes some practice to get right
unfortunately, on the bridge it is hard to hear the bass, but the
progression is |A|A/E|A/G|A|A/E|A then back to the verse
with hammer ons, something like
D 6h7 6h7
A 5h7 5h7
and then repeating. Sorry if there are any mistakes :-)
