the main riff:
-----------------------------------------------------------------|
-----------------------------------------------------------------|
--------5-7-5-7-5-------5-7/9-9------------5-7-5-7-5-------------|
--7-5-7-----------7-5-7--------------7-5-7-----------7-5-7-5-2-5-|

you can make little variations where the 7/9 is, like:
---------------------------------------|
------------------------------7-9-7----|
--------5-7-5-7-5-------5-7/9-------9--|
--7-5-7-----------7-5-7----------------|

the bass solo goes like this:
--------------------|
--------------------|
--------------5-----| 2x
--555-5-55-77---7---|
