Watch the Percussive online guitar lesson by Robben Ford from Rhythm Revolution: Vamps & Jams
On this tune, I'm more so serving the role of the drummer, acting more rhythmically rather than trying to impart anything harmonically. I'm also avoiding playing the 3rd in the chords here, which makes it neither major or minor; just the sound of the guitar, which is what you want. You can add some flourishes here and there to impart a little more of the guitar's sound, but just enough to let people know that it's there. This leaves a lot of room for a keyboard player or soloist to move about the song.
Don't forget to take advantage of 4ths as well. The first time I'd heard this incorporated into jazz was the music of Miles Davis as well as Herbie Hancock, who really used it in his music.
Don't be afraid to re-embrace the guitar as a rhythm instrument. That was its role before it became a soloing instrument, so take advantage of it as often as you can.
