I would like to improve my guitar solos and to add a lick to them. The one I'm thinking off is used in many blues songs, but also rock'n'roll, punk rock, etc. One example that I can find is the whole outro to this short video.
The riff is also used, for instance, at the end of Feelings by The Offspring.
What is the name of this riff? I tried to look it up but the only things I find are compilations or 10 guitar riffs to learn, none of which contain it. I tried to pick it by ear but I can't manage to be as fluid as I would like, so I guess there is a technique I'm missing.
