This week we're going to be expanding on the simple phase inverting circuits we made last time, this time adding a bit of voltage control to make a Phaser! This circuit shifts the phase of a selected range of frequencies, so that when you mix the phase shifted frequencies back in with the oringial, you get a really thick sound. It's a pretty simple circuit using Op-Amps, a few resistors & capacitors, along with a JFET based voltage controlled resistor (VCR).
