Bill, I think you and I are taking the same approach on learning songs. Like you I have been working on refining my ability to play a song as close to the notation as possible in time. I have learned the same lesson…to just slow things down, count it out and get it firmly under my fingers before I attempt to play it up to speed. One of the songs I have been working on is Shook Me All Night Long by AC/DC which I know you appreciate! I have the rhythm down pretty good so I decided to try to play the solo (lead playing has not been my strong suit but I would like to get at least competent). I am working on playing it slowly in time and the first half is coming along. In the process I have learned how to play pinch harmonics which is super cool (Anders has a great set of lessons on GT) but I still find playing vibrato with my index finger remains an ongoing process of improvement more so when I have to “pull down” than when I “push up”. I know the wrist action is critical but it seems like it is taking forever to build up speed.  But I figured the best way to improve is to play in the context of solo so I can hear it in context.  

Thanks for the tip on Soundslice. When you feel like you have Lazy down to your satisfaction post it. Your dedication is inspiring and I enjoy hearing about the progress you are making. 

All the best, Mike
