I was looking through the shop and wanted to buy Sungha's work but I want to know about the content of the CD. Is there anything else inside "Sungha's Signed CD" other than Sungha's signature? and what's the difference between "Sungha's Original Set" and "Perfect Blue MP3 Set"?

If possible, I would like to buy the one with signature as well as the tablature pdf. I'm learning fingerstyle, inspired by Sungha :)
