Great information all - thank you! I am trying to work with everything suggested here and I have my work cut out for me.... I'm also at the limits of my understanding of a lot of this, so bear with me if I'm not getting it. I see that I need to go back to some basics and learn more scales, for starters. Beyond that, to respond to Fred about what I'm trying to do - first, no rock, only folky stuff and maybe some blues. I'd like to get some insight for starters on runs, getting from chord to chord with somthing more creative than what I've been doing for years. Then, I also want to learn to pick out some lead stuff - whether actual replication of the melody, or licks that complement the melody for guitar breaks between verses.
Thanks, and keep the advice coming! Lane
