The player I have heard this from the most is the great Eric Johnson. However, I am sure there are many players that use this technique.
Grab the TAB for the video lesson below.
The concept is actually very simple. You will be picking directly behind the note you are fretting to create a very thin and bright sound. That is accompanied all most simultaneously with a quick bend and release with the fret-hand.
You will then pull-off to the note you are holding in your fret-hand.
I suggest starting out by using mostly pentatonic scales with this technique then perhaps experimenting with other scale types.
Also, if the index finger of your picking hand isn't used to fretting notes (which it probably isn't), I suggest just practicing this technique a couple minutes a day until you build up a callus so that you won't get a blistered finger. 🙂
