I have been trying to play blues and country for the last 6 months, I am still not as successful as I would like to be. I would like a sound track, and a practice pattern, that progressivly goes from slow to normal speed. So I have bought Riffmaster Pro. It slows down the riffs , but does not distort them. I will see how this works. I find that most songs I can't keep up at normal speed. I have been trying for about 6 months, but my fingers will not work that fast. I am 78 years old which may contribute to a long learning curve. I will keep you posted. Mike
