I am really pleased and very happy, since one of my dreams just came true! I use this program since I started playing the guitar. You must know it as well if you are a guitarist, since most of the TABs on the interternet is in this format. Basicly if you play instrumental music and you want to learn a song you just search for it and in the 90% of the cases you will find a tab which you can only open in this program. And it also plays for you so it is very good for learning since you can slow all the songs down and just play along with the them.
I started tabbing few years ago and I made all the things that you can find in this website with this. So when two weeks ago they offered me the endorsment I was very happy. Now I am among their international artists and also one of my songs (Italia) will come with the program and you can download from their website or my website for free.
I guess now I can say it was worth to start to play the guitar!
