My voice turns into a buzzing gazoo-like sound when I hit the higher notes.

Does anyone else experience this?

When you start going higher (properly, with your head voice) and you hear a buzzing sound, like your voice literally turns into a gazoo.

Maybe it's caused by nodes on your vocal chords?

Any advice is greatly appreciated.

Hard to say without hearing you, but it could be a slight seperation of your cords from not supporting well enough to keep good cord closure. It happens to me sometimes.
