Believe me, if you really want to learn regular guitar well, go to a private tutor. Not even in college, let alone in a musical instrument store. They are all quacks. Please recommend a good teacher to you. Find Mr. Gao Kai, who is known as an all-around guitar musician after 1980s. As long as you can find him to teach you, there is no problem at all. Don't find a substitute teacher. I looked for him when I first started in 2009, slowly.
