I got this one working. Its a versatile phaser. But I got a volume drop when engage.
is there any way to take it to unity?

schematic was taken from pedal PCB

You may have an error. That plan should give gain of 0.99 naturally.

I just built this the other night on the pcb I have no noticeable volume drop.   I'd think as prr said there is likely an error.
