First off, this is the best guitar course on the market. I took three other in person courses and all they did was get my money. They were half hour courses and what can you retain in that amount of time. I'm probably one of the oldest guys, 75, taking this course but as you get old, if you don't use that brain, it slowly goes to sleep on you. When I started this, I had a buzz in my "A" string and after fighting that I found out it was how i fretted. On the Blues shuffle I can play along With Tony but after printing a hard copy and trying to read the tab, I get a little mixed up. Just have to get my brain shifted to a higher gear. Two words a guitar player should never use are I CAN'T or I WON'T....
