Here are two examples of what I prefer to think of as humbucking/overdriven tubes tone:

They're both somewhat more trebly than the old Santana/Page stuff, but that can be adjusted downwards
after the amp stages - that would usually be done by speaker choice. Petrucci uses a lot more preamp tube drive, obviously. They both play Music Man guitars, bolted maple necks with I believe basswood bodies. Let's face it - any guitar is generating certain frequencies, every cord, stompbox, tube, speaker cabinet, speaker in the chain affects the overall EQ -
there are many ways to get to the same tonal style. If you're starting out with an adequate amount of treble, midrange, and bass from your guitar, the tone is determined by the
proportions of frequencies and how you overdrive them, and then how they're
RE-equalized by the following elements of the chain.
I pay close attention to what people are using, but you have to
listen well more than anything. Every guitarist should at some point buy a cheap $50 rack graphic equalizer off of Ebay and fool around with it, so that they can get a grasp of what frequency proportions cause what
they consider to be "good" tone. Or, just keep buying pickups and amps and guitars and stompboxes till you have a million of them, and still don't know doodly-squat about
why things sound good.... :help: Here's a starting point:

"the pre-clipping frequency equalization and post-clipping EQ are absolutely critical adjustments. Once you have a well-behaved clipper -- even if it's just simple diodes, as in the stomp boxes -- it is the precise combination of pre- and post-clipping EQ that mostly determines how an amp sounds. The 'secret' of the best sounding guitar amps lies in the pre-clipping EQ response curve."
Van Halen's guitar tech recommends an EQ pedal above all, as the most valuable pedal, in his book Guitar Gear 411: Guitar Tech to the Stars Answers Your Gear Questions, pp. 75-76.

"First, it's important to have a concept of good tone - no matter what it is. And then the rest is just finding it."
