Watch the Electric Groove Rhythm online guitar lesson by Jeff Scheetz from Blues-Rock: Secret Sauce
This rhythm has a Hendrix vibe and would go over great at any local jam night. If you play this rhythm for your guitar buddies to jam over-- they should love you for life!
Keep focused on the groove - timing is everything when you are playing this kind of riff, just make sure you are in sync with the drums and you'll be fine.
Try experimenting by turning your volume up or down until you "feel" the groove that's right for you.
