[sdiy] SSM2164 Phaser - another way?

[Tom Wiltshire]

Hi all,

I know that phasers with the SSM2164 aren't anything new, but I wondered if anyone had tried this:

It looks ok in the sim. It breaks the usual rules by taking the output of the SSM2164 to a genuine ground rather than a virtual ground, but I can't see why that should be a problem - is it?

If it works, I think it saves one op-amp per stage over the "usual" APF version, like Hoshuyama's:
