[sdiy] SSM2164 Phaser - another way?

Hi Tom,

> Ah, dagnammit! I bet you're right. It'll make a notch, but it won't move.

Yes it does exactly that - I've just simulated it myself in LTSpice
and I get a fixed notch at about 113Hz.

> Yes, I was thinking that because you've got a variable current at the output, I could treat it like a variable current *going through*. But of course it doesn't - it pulls the current from the rails instead. The input current won't change at all.

> Oh well. One day I'll find a way.

Good luck!

Neil
