Download Classic Phaser:

Analog Modelled Phaser Effect

The Classic Phaser VST plugin by Kjaerhus Audio emulates analog phasers from the 70's and 80's, enabling it to resemble anything from phaser pedals to expensive studio phasers from that time period. The Classic Phaser effect features 4 to 12 filter stages, an LFO rate ranging from 0.1 to 10 Hz, stereo spread, host synchronization, and filter and feedback depth controls.
