I have the same problem on some of the play along jams; their to fast. Every teacher say's to start slow and work your way up to speed. Lessons should have the option to download the play along track, then use programs such as Song Surgeon or Amazing Slow Downer to slow down the tempo to the speed you can keep up with and then start speeding it up. With Song Surgeon you can add a click-in before the it starts playing. Without the count-in its already a few seconds into the play along before I can get my hands back on the guitar from the mouse. Both programs also loop sections and repeat them over & over. Great learning tool.

Another option would be for GT themselves to make sure all play along tracks have a count-in, slow down features, and looping of sections.

The GT lessons are great as is, but everything can be improved upon. For example, GT should require all teachers to use a standard lesson template for their lessons. This would make every lesson format exactly the same.
