Watch the Carl's Shuffle 9 online guitar lesson by Carl Verheyen from S.W.A.T. Blues
As I said in a previous lesson, the best of us are only truly improvising 30% of the time. The rest of the time we're stringing together lines and licks we've worked out in a given key. The more time you spend doing that the stronger and more interesting your playing becomes. Influences meld into your style like a river flows into the ocean.
