Harmonics or Feedback Techniques

[zaverill]

Can anybody give me som hints as to how to perform those squealing vibrato effects like Ozzy's No More Tears? I've seen Zakk Wylde do it all the time and i thought it was from pinching a string or using a reverse whammy tecnique by tightening the string rather than loosen it. It doesn't appear to be either. Any ideas?

Throw your guitar down a flight of stairs with the amp on. That'll do the trick almost everytime. :D

........Nope, that didn't work. Anyone else out there who knows?

bridge pickup with lots of overdrive/dist.

it really helps to have humbuckers too

you also have to somewhat search for the sweet spot which will give you the loudest clearest pinch harmonic
