I currently have GB 6.0.5 and have been using it to learn Blues Guitar. I was thinking of updating to the new 10.0.2. I was hoping there would be more Blues content such as new Lessons. Does anybody know if the newest GB has more Guitar Blues content? The other hesitation I have in downloading the update are the many poor Reviews complaining about everything from extended download times to features that no longer exist or work poorly. Anybody that has upgraded to the new GB, was it worth it? Thanks!
