Hey Nightradio, I was looking at your mono phaser, and when I saw there was only one pole (one allpass), I was going to come on the forum to say you need at least one more pole to get a notch. Then I played it. Why does the single allpass create a notch? I thought one allpass offset the phase by only 90 degrees?

After more testing it seems like the standard allpass filter has 2 poles baked in. Interesting
