Great guitar players started from scratch. Like the rest of us, they were also beginners in their craft before they became the music Gods they are today. In truth, they probably had a hard time with their setups too and had a little help from friends or articles before they became experts at guitar action and playing.
They weren’t always playing for a huge crowd or the arena. Most of them had the humble beginning of practicing in a makeshift stage or their own garage. Some have even met with failure before they became successful. If someone wants to be like them, the individual has to realize that there are a lot of things he needs to accomplish before he truly becomes great.
