can someone explain to me what a artificial harmonic is and how to play it. I was reading a few tabs and i don't know what that is.

Artifical Harmonics are no different that the conventional harmonics. Its the same thing. They are just in reference to the enharmonic scale as opposed to the harmonic or major scale. Kinda like c# to Db. It depends on the key signature. Its all theory.

Just turn your gain up and pinch the string a bit to get the harmonic squeel. Sounds like thats is what your after.
