Hey guys,
I love Mike's work and am pretty familiar with it. I cannot for the life of me though figure out what he is doing to get this shrieking noise of his out of his guitar. My general guess is maybe a modified wah pedal of some sorts and a **** ton of feedback...but I really dont know. I have an application for it in my band but have had no luck replicating it. If any of you know what is going on or have created this kind of sound please enlighten me on what I need to do to make it happen.

Thanks a million and rock on! -Rob

Use a wah pedal and play a note and touch the string to make a harmonic ring out as you sweep the wah up.
That my friend is the sound of a wah pedal in an effects loop.

effects loop? no.. pinch harmonics.. sounds like it.. he places his hands on the strings just after he plays the chord... position of wah emphasises the higher frequencies as well..
