I'll never understand why people say things like that about guitarists who aren't "famous".
Petrucci is just another guitar player, when I was at NAMM I heard 100 different players who all played just as clean and fast as he does but aren't famous. Remember the best guitar player in the world is probably some kid who will never leave his basement.
In all honesty, I think Petrucci, Vai, Romeo, all those guys are wicked, but I have heard guitarists in other genre's that could smoke every one of them in speed and clarity. I don't judge how good a guitarist is by how fast they can play that's for certain. I can play as fast as I want when I want to, I spent many years developing speed techiniques, but that doesn't really do it for me.
I'll see if I can dig up some recordings I have that are more recent and try to get them online. I'm far from a phenominal guitar player, after being at NAMM, I don't even know if I consider myself that good anymore, but I enjoy it so that's really all that matters. For a challenge to myself I like to play the most technical stuff I can. Petrucci is fast and creative, but on a technical level he's not doing the crazy things like Romeo is. Romeo was the reason I learned multi finger tapping, Gilbert was where I learned string skipping, for pure technicallity, Romeo and Sy X are one of my favorite bands. Don't get me wrong, I love DT, I really do, they just don't amaze me anymore. Their newer stuff is getting boring, old DT is where it's at AFAIC.
Anyway, here is one song I do have online, it's about 5 years old and was written, sequenced, and recorded all within about an hour after I was mugged one evening.
The guitar tone sucks, it's just straight into a boss BR8, but hey, it's all I have on here for now
enjoy.

nice guitar solo
some of the whammy bar is slightly vai-like, but that's not a bad thing.
to make this post related to dream theater or something, the music in that song is a more classic rock than prog rock type of thing. not very dream theater, which isn't a bad thing, lol.
