Watch the Country Train online guitar lesson by Jim Campilongo from Sonic Tele
Here are some licks in E, A7, B&. If you are new to behind the nut bending, I recommend going slowly and getting a feel for how the different bent notes sound. Don't be afraid to dig in and test the sound of what you can do behind the nut. Try gradual bends, quick bends, bends of varying degrees etc. Once you are comfortable, you will start to get a feel for the technique and can really start to open the door to some very expressive playing.
