Starting off in the key of Em Stuart shows us the basic technique for one string tapping that gives you a foundation to grow from.
Start slowly take your time and don't expect miracles. Once you get comfortable with the interface (your finger is doing all the work) you may be ready for the rest of the exercises which get faster and make it harder to keep up.
 There is very little melody in what we are taught. Its mostly about building mechanistic speed and moving about the neck. Its a technique guitar lesson after all. You can call it shred when you can do it faster.

But you will be learning and you don't have to do it that fast to get a lot out of it and to learn way cool new note relationships.
Anyway I like these three note and four note arpeggios runs using the tapping technique provided I have the right sound.
I am running my Fender made Charvel San Dimas through a line 6 Spider Jam with it set to 'insane' with low volume. I tried it clean and it works that way too so use what you have.
Your 'finga' will still get sore. This is work. In Ch. 2 somehow I get lost with the patterns he is using and have to slow it until I get that original technique he showed us first.
