Hi Mike: I've enjoyed your lessons for some time and just wanted to say thanks for all of your work on Guitar Tricks. I've recently found the Boston lessons, and in particular, Peace of Mind to be really helpful. The leads are slow and melodic enough that I can play and remember them but they also require enough technique that they've really improved my vibrato and full step bends with vibrato. I didn't realize how weak I was in this area until I saw the improvement. These lessons are a real gift for anyone that wants to learn or improve their guitar playing. Really appreciate what you do for us.
