Watch the Slow Blues online guitar lesson by Jeff McErlain from Blues Guitar Survival Guide - Lead
I know I sound like a broken record here but it really comes down to a few basic things. You must know the names on the neck cold. You must know the notes in each chord cold.You must understand basic major scale harmony. If you work on getting these three things together your playing will take off, I promise. The bitter pill here is that this is non negotiable, you play guitar, learn the thing! I can say this with complete confidence because I made that commitment years ago and that's when my playing changed. I see it every day with my students as well, the light blub moments they have after becoming literate on the instrument. Don't be illiterate! Commit! Do it! Plus it's fun.
