Hey cruznbenicia,

Thanks for your post! You can certainly use your thumb to hold down the low e string. Here's a lesson that will help you on that: http://www.guitartricks.com/lesson.php?input=14463

Also, if there is any moment where the instructors are moving to fast, you can always use the a/b loop feature on the video player to stay at a part in the video you are still working on.

Best Regards
