John Petrucci

"With the amp in the effects loop is actually the Axe-FX II, which we just started using. We were using the Ultras before. The guys from Fractal took all my programs from the Ultra, and [John] only uses one preset, it's all of the effects just kind of like you would have in any other system - delays, choruses, whatever - and we just turn them on and off. They're set, they don't change. So he programmed everything into the Axe-FX II, came out, we put it in the rig and sat there and kind of had to go through stuff and tweak things a little bit. So with the Axe-FX II, the outputs, left and right, come into the effects return. The top amp would be the left side and the bottom amp is the left side, so we get a true stereo thing happening. His effects chain is just very, very simple. Everything is in parallel with the main line of it, so there's nothing too crazy going on," says John Petrucci's guitar tech.

In this tutorial, John's rig is shown to consist of a Fractal Axe-FX III.

"We're using Axcess Electronics so here is the old, trusty FX I. This gives John complete control over his rig. I've got six preset buttons: one and two are clean; three and four are rhythm; five and six are lead tones. Then you have all the instant access switches for all the different effects: the chorus, all three delays, the harmonizer are in the Axe effects. Then the flanger, phaser, tube screamer and compressor are in the satellite pedalboard. And then he can just kick stuff on and off at random. It is beautifully labeled. I got to say that Thomas Nordegg, Steve Vai's tech, made those for me. The random switch is right now not doing anything. That's for a future endeavor that goes along with the JP chorus button. I just had the labels made for future use, but right now those two don't really do anything. All the other ones go to a lead preset, it gives them a delay and a solo function on the amp," says John Petrucci's guitar tech.

This is a picture of the rack John used for the 2002 World Tourbulence tour. Among the various units there are two TC Electronic 2290 delay units (third and forth from bottom to top). Confirmation of this being John's rack can be found in this diagram from Guitar Geek and at :15s in this video.

"In the electric [signal path] side we come in and hit the Dunlop Wah system first and then out of there we actually come up to this little satellite pedalboard," says John Petrucci's guitar tech.

Another cool thing we used a lot is TC’s 2290-DT plug-in with the desktop controller. The 2290 was always a staple in all of my rigs, all my big refrigerator racks. And the plug-ins really sound true and authentic. So we ended up getting Ben Grosse one, and he used it on the mix. Whenever you hear a chorus and a guitar, that’s what it is.

The JD7 proved to be a real asset during the recording and the best part was that my tone and the guitar's response remained true. I purchased it after we were done!
