The quality of a few older lessons are subpar, they should just remove those or reshoot them. For example, there is a teacher called Hanspeter Kruesi, who seems like a nice guy, presents useful content, but the 360p lessons shot YouTube style at his house in front of his PC don't live up to my expectations. I'm just talking about a few lessons here, but still.
The lessons are organized and categorized in several different ways, which is a must, given the number of lessons available. You can search according to skill level (absolute beginner, beginner, easy, intermediate, advanced and extreme), which saves a lot of time because you don’t have to search through lessons that are too easy, too hard, or just not your thing.
You may have gone online to look for guitar lessons or to learn the fundamentals of guitar. Even if you just want to learn a few particular songs and increase your knowledge a bit. Even if you are an experienced player, this may be the place to learn that little nuance that you may have felt was missing from your method. Either way, this is the website that you will want to continue to visit.
As a beginner, it is best to avoid making a pawn shop, flea market, or yard sale purchase unless you are shopping with somebody who has experience in purchasing a guitar. Having never purchased a guitar, you may not know what to look for in terms of damage or guitar quality. With that being said, a local music retail shop is your best bet. You may also shop online with a reputable company, although be sure to review the business’ return policy.
