Hi! I have been playing guitars on and off (mostly off) for over 20 years. Technically I feel competent and can physically play anything I would want to play. My issue is I don’t feel I really know much about the guitar and don’t really progress. I don’t have much of a repertoire and just know a handful of licks and half songs. I want to dedicate some time the next 6 months to learning but not sure where to start. If it helps I’m mostly interested in blues/jazzy stuff. Any advice?
