OK....I guess not many people is going to watch this till the end, unless some Satriani's psycho-fans. I didn't play it perfectly because my guitar playing skills are way much lower than the master Joe.
There was no need for me to use the 7 strings guitar, I used the guitar because this is the only one Ibanez I have and it has the sound close to Joe's more than my other guitars. The other reason I have used Ibanez guitar is that the Satriani's psycho-fans will never forgive me if I use other brand ;-)
The backing track I have downloaded from the internet very long time ago (don't remember the site) if someone want the track send me a message.
