I just uploaded my favorite dual tones to CustomTone. Two different themes here.
Crunch + Clean
Combining two amps, one higher gain, one less gain. I pan these hard left and right, and add a short delay to one side to give a really nice stereo separation. Works well in a live setting if you can get two channels on the mixer (tell the sound dude, c'mon, you give the keyboardist two channels!).
Fender Twin Reverb + Soldano SLO 100
Marshall Plexi (variac'd) + Vox AC-30 (clean-ish)
Marshall Plexi (variac'd) + Vox AC-30 (crunchier)
As noted in an earlier post, a studio engineer I ran into told me one of his "tricks" for mic'ing a guitar amp is to put two mics on the same amp: one on-axis, one off-axis, and pan both mic's to the center. That's not too hard to set up in a studio, a little more challenging in a live setting, but with a POD, it's a piece of cake. So what I did is took some of my favorite amp models, and create a dual tone that does just that. Each of these tones have two amps, set up the same way, except one is mic'd on-axis, one is mic'd off axis.

Enjoy, people! You can find them in the CustomTone under the POD X3. The easiest way to find them search for my userid: brian6string.
