This is a wonderful “hybrid-picking” style that is based on the piano style of the great Fats Domino.

It involves the "tri-tone" theory, wherein the seventh and third, become the third and seventh from the I to the IV chord, but more importantly, it's a very deft and acrobatic way of playing a three-note pedal steel riff on the guitar that has movable parts!

Here's one of my favorite positions when it comes to making the guitar sound like a pedal steel.

This is one of the first “variations” we can come up with within the “block” chord major pedal-steel lick position.

It involves a wonderful use of pick and finger, or “hybrid” picking for a banjo kind of effect, while the left hand is playing a classic “pedal steel” kind of bend position for open G.
