And the phase shifter is now complete, too!
A fair amount of op-amps in there! It is a 4-stage, 720-degree phaser. There's a wet/dry knob to control a mix of the original signal & the phase shifted signal, which is ideal for effects. I only tested it lightly, but it seemed that the frequency knob didn't do much above 2:00 - perhaps it was just due to the setting of the original waveform, as it clearly did a lot to the signal before it got to 2:00! There's a VC input for this too, but I haven't played with it yet - since it is summed with the frequency knob, however, it should work just fine.
