The Kn² Phaser VST plugin models a late-’70s JFET-based phaser.

Featuring four main phase-shift stages and an additional stage operating in the opposite direction within a variable feedback configuration, this compact pedal can produce a wide range of sounds using only two knobs.

The model features two controls: Rate and Recycle. The Rate control adjusts the LFO frequency, producing anything from slow phasing to rapid warbling, while the Recycle control adjusts the gain of the feedback loop, effectively emphasizing the peaks between the frequency notches to create a more nasal, almost wah-like effect.
