detune

Detune is a pitch effect that slightly shifts a signal's tuning, often by splitting the signal and detuning one part for a chorus-like result¹². Sources describe it as an onboard polyphonic pitch effect, such as a stereo detuner³, and as a mode on pitch pedals that mixes a subtle pitch shift with the original tone for a spacey, ambient sound⁴. Boss's Detune mode provides chorus-like effects usable with three-voice harmony⁵, and DigiTech's Detune presets sound lush and organic thanks to unpredictable wavering⁶. Detune also appears as a control on chorus pedals, where it shapes the intensity of the modulation⁷⁸.
