Ok, you basically follow this chord progression
Am - F - Cm -G
(I'm gonna give you the grades instead of the names of the notes or the frets to play, so it's root, 2, 3, 4, and so on)
Am: [R - 8 - b7 - 8 - b10 (that's a b3 but an octave up) - 8] - 5 - b7 - 8 (repeat first part)
F: R - 8 - 3 - 5 - 3 - R - b7 - 5
Cm: [R - 8 - b7 - 8 - b10 - 8] - 5 - b7 - 8 (repeat first part)
G: R - 5 - 5 - 4 - 5 - 4 - R - b7 - R - b7
Now, If you're used to tabs, this may seem like a cruel joke to you. I'm sorry for that, but try to see if you understand the system and keep in mind the following:
The bassline is played pretty fast, but it's not drowned in the recording, you should be able to hear it pretty well.
Some notes are struck twice, like the first octave.
Begin playing without the recording, every note being equal in duration… I'm sure in some minutes, once you get comfortable with the line, you'll start really "hearing it", then just adjust the notes duration based on the recording.
Hope this helps, let me know if you need any clarification.
