i can't listen to the neo-classical stuff for very long. my biggest early influences were Gilbert, George Lynch, Warren Demartini, Vinnie Moore, Yngwie, Greg Howe, Marty Friedman, Nuno Bettencourt...of those guys the only ones i can listen to for more than a song or two are Howe and Moore.
I do still really enjoy Andy Timmons, Richie Kotzen (one of my favs), Andy James, Jeff Loomis, Guthrie Govan, Joe Bonamassa...along with country guys like Paisley/Mason. I like fusion to an extent....but sometimes guys just get too out there for me. I enjoy hearing outside playing as much as anyone....but when there is no melody or tonal center at all it just becomes noise to me.
of course you can't play modern worship music without being influenced by U2/Coldplay...so they are big influences along with Muse. (LOVE that band)
