I love Ritchie Sambora's Solo to Dead Or Alive which for me is a perfect example of pinch harmonics. Perfect because it conveys a certain feel of aggression and tension. The executional problem comes when you have a fretted note and you want to produce a pinch harmonic different from the fretted note. You then have to imagine where the fundamental nodes on the string lie in relation to the fretted note, for example hahanapin mo kung saan na ang node para sa half the string which is easy but for the equivalent 3rd, 5th, 7th, 2.3th etc. Finally, in addition to what was said above about distortion and gain, I would say a Bareknuckles set of pickups would help because generate harmonic, so far in my experience, it is the only set of pickups that are sensitive to note overtones that it makes it easier to do pinch harmonics. Put on a rich sounding guitar with the right amount of gain, it can do pinch harmonics without the player having to know the fundamental node positions.
