Having just completed (and enjoyed) Matt's Advanced Keyboard Techniques course, it struck me that a similar course on guitar technique would be really useful.
Although most people are probably using a keyboard MIDI controller, if you are using a half-decent guitar VI like MusicLab RealGuitar, you still need to know how a real guitarist plays, to get realistic results. Many of the courses mention things like pentatonic scales and power chords in passing but a course that covers rhythm and lead guitar techniques for rock, jazz and folk would be really useful. Things like chord shapes, bends, mutes, hammer on and snap off and other articulations...
I bought the Guitar for Dummies book which was very useful but seeing it in video rather than the printed page would help to reinforce it.
What do you think?
