Have there been any changes to your guitars and rig?
Satriani: "In the space between the two Chickenfoot outings – our last tour and this run of dates – I've moved completely to using the Ibanez JS2400. I did the Black Swans album and tour and Chickenfoot III with the 2400, and it's really something how going from 22 to 24 frets can affect your playing.
"You might not think that two extra frets can change what you do, but the difference can be huge. There were a few times on stage when I'd actually look at the neck and go, 'Now where's D? Where's E?' [laughs] It's funny now, but it wasn't so funny at the time.
"There's something ergonomically pleasing about having those two extra frets. Plus, you can play higher notes, which might not be so good for the general public. [laughs] And the guitar just sounds better to me."
As you said, one doesn't think that two extra frets would make such a difference – especially for somebody who knows his way around a guitar neck.
Satriani: "It's nothing I've talked about before. Doing these shows has been very important for me as a guitarist on stage. I felt really, really good, and I was able to go from traditional playing to all-out craziness, a real loss of control almost. So with the 2400, it's been an ergonomic thing, but I feel very much at home with it now. Plus, I think the balance between the bridge and neck pickups is right there. We hit a really good, sweet spot.
"The only other change is that I started using this reverb pedal called Wet. I got it about nine months ago, and it's great. It's got such a nice reverb tone to it, it's almost mysterious. I've tried a bunch of things over the years, but the Wet pedal really impressed me."
