Built with true analog-style bucket brigade circuitry, this plugin is a modern reissue of some of the most iconic hardware units, faithfully capturing their distinctive tone. The effect ranges from subtle doubling to rich, swirling modulation, covering different uses as a Chorus, Flanger, or Vibrato. The expanded modulation controls, multiple characters, and LFO waveforms allow precise shaping of your sound, giving you complete creative flexibility. In addition, the feedback control adds rich, flanger-like textures for dynamic sonic effects. Under the hood, the plugin uses two individual delay line paths. Each path’s behavior is determined by the character parameter: Thick and BBD provide warm, classic BBD-style tones, while Clean delivers a more transparent tone with greater modulation. This chorus has become a favorite in the iOS music community, combining vintage inspiration with modern control to deliver professional-quality sound in any production. This is an AUv3 Effect and requires a compatible host to work The in-app purchases are for tipping only, the app is fully functional without them The documentation is available at fredantoncorvest.com/FAC_Chorus.html
