Those created by the phase cancelation, when the phse shifted signal is 
mixing with the original signal.

Set the A-125 to zero "resonance" and "mix" fully clockwise (no original 
signal), sweep the "shift": you don't hear any notch and not 
phaser-effect at all.
Now turn the mix back to 12oclock position, but still zero "resonance" 
and sweep "shift": you will hear the notch now.

if you add "resonance" you will have also some kind of mix. That is why 
you hear the notch with resonance and mix fully clockwise.


To explain in detail this I would need some graphics. Maybe I will do 
this some other day.
