I'd second Jive's advice. Absolutely. It's all triplets in some form. You must learn to think in triplets, just as you already know how to think in straight time.
When you listen to the bass lines, listen for ghost notes that reinforce the triplet feel. In Jazz, you are mostly going to be walking 1/4 notes. Ghost notes between the strong pulse of 1/4 notes will drive the swing factor through the roof. Don't interpret this to mean that plain O' walking 1/4 notes can't swing. Just listen for the ghost notes and copy the placement of them.
It seems that you are really asking about the feel in general. I would off the following additional advice:
- practice plucking in a swing/shuffle pattern whenever you can - even without a bass. Lead with your ring finger sometimes and your index other times. This will help improve your weaker direction. For me, I'm dominant in that I lead with my ring and hit my index on the beat. It's almost like the index is a grace note. If you work going both directions, it will improve all aspects of your groove.
- the music you listed is all about the GROOVE. IMO, there is no point in playing it if it doesn't groove. So, with that in mind, work hard with the metronome. Try to make it swing with just a click. Forget the drum machine for now. Just a click.
- Since you come from a rock background, you might try some ZZ Top. Rock and blues slammed together. Tush, and La Grange are both great songs for practicing shuffle playing. They are easy and repetitive. Just what you need.
PM me if you want some specifics about Johnny Lang or KWS. I have played a bunch of that stuff.
Good luck and keep a positive attitude. Patience and persistence are the keys here.
