as far as exhale squeels go, I'm still sort of stuck. I know the tecnique, how to do it and everything.

however when I do it and I pinch the air, it comes out more of a distorted guttural with a minor overlayer of the squeel, but more breathy then an actual "reeeee".

where as inhalewise i can easily do "reeee" however it does'nt have the low with the overlayer such as doing it exhales.
