When I started playing the guitar, one of the techniques I had a lot of trouble with was fast alternate picking.  When I sought the help of some friends of mine, I kept getting the same advice that was not working for me.  As I started looking for ways to improve, I found this wonderful site on the Internet.  Within a few short weeks, I was making amazing progress.  I can say with confidence that the information on picking is so valuable.  No other resource has been so valuable in my quest to be an accomplished guitar player.  I will certainly recommend this site in the future.
