From the developer:
Modeled after vintage analog phaser circuits, Blue Cat's Phaser reproduces this old vintage phasing effect that you can find on so many recordings, but with the precision of modern digital processing techniques. You can choose to apply up to 32 phasing stages, pushing the model to its limits, or create a subtle phasing effect with wet and feedback parameters set to a few percents.
