Our friends at GuitarMasterClass.Net took 40 common and not-so-common guitar-playing techniques and put them together in one solo, as shown in the video below. As it turns out, this is a great way to survey a range of techniques and pick up some that you might not be familiar with.
In this video, Sinisa Cekic takes you through such techniques as pre-bends, normal and strict legato, banjo rolls, chicken picking and numerous picking techniques, and vertical, horizontal and circular vibrato, plus many more.
One of the cool things about GuitarMasterClass.Net videos is that they often provide all the tabs, backings and scales included in the lesson. You can get everything at this link.
