Very honored to be a part of this !
I used the Axe-Fx III on it. A little secret : the song is in C, but I'm tuned in Eb. I wanted to play it in C, but didn't want to re-tune/re-set my guitar (a pita on a Floyd Rose type bridge). And as Satriani signed it, I wanted to use this one ! So, I transposed the backing track, recorded my part with a dry track, and then re-amped a pitched version (+1 semitone) of the DI track. And it doesn't even sound like it wasn't played in C
