Ok - I've been busy trying to learn SRV's
Cold Shot for the last couple of days, and there's a part of the rhythm that just has my brain rattled.

I know all of the chords and notes to the song (and working on the leads...) but what has me absolutely baffled is the way he rakes the strings right before each note of the rhythm part. If you can't picture what I mean, then feel free to download and play the song from the link below. He starts doing it immediately in the first bar of the song.
I have tried and tried to duplicate that sound - I figure that he is muting the strings with his left hand, and then un muting it just in time to play the single note, then muting it again, playing the single note etct etc. I have tried muting with the left hand only, the right hand only, and a combo of the two. Cant get that sound.
Does anyone have a clue how he did this???
Here's the tune -
Cold Shot
Hope somebody knows!!!
