This is a picture of the rack John used for the 2002 World Tourbulence tour. Among the various units there's an Eventide DSP7000 Ultra Harmonizer (second from top to bottom). Confirmation of this being John's rack can be found in [this diagram from *Guitar Geek*](http://www.guitargeek.com/john-petrucci-dream-theater-guitar-rig-and-gear-setup-2002/) and [at :15s in this video](http://youtu.be/4yUUCRJGdko).more
On his SoundCloud's account comments, another item that Richard David James mentions as gear that he uses is the Eventide DSP4000: "Really inspired me, thanks Tom, he gave me some of his patches, awesome stuff, wouldn’t want to use them of course, they are his. He made some synths on them which was some great lateral thinking at the time. Never rinsed my DSP4000 anywhere near as much as he did but I’ve been recently been giving the 8000 a REALLY hard time with the Cirklon! inspired greatly by Tom."more
