Tower of Power -- On the Serious Side

[jitter]

Hi!

 

I'm trying to transcribe the cool unison riff from Tower of Power's On the Serious Side (on the In the Slot album). My ears tell me the bass is playing the riff like shown in the image below and the guitar is doubling some of the notes (one octave above), e.g. on 1, 1+, 2, 2+,... but not on 1e and 1a and so on.

Correct? If not: what's the correct riff?

 

Thanks in advance,
