The Source Audio Gemini Chorus stacks the choir not only with a trio of lush stereo effects, but also the technological execution under the hood this company's staked its name on. Sporting a single-voice Classic mode reminiscent of 70s choral effect, a creamy Dual mode for double voicing, and an all-out '80s Quad setting for enormous tone, this is only the opening act. Part of the Gemini series, this pedal can connect with Source Audio Neuro app for downloading an enormous library of additional effects and parameters right onboard.
