| + | [[Electric guitar|Guitar]] and [[bass guitar|bass]] chorus effect may be simulated with an audio signal processing unit, which is in many cases seen in a pedal format (known as **chorus pedal**), <ref name="guitartone1">{{cite GuitarToneOverload.com|url="http://www.guitartoneoverload.com/2010/09/26/how-to-use-modulation-effects-part-3-the-chorus/"|title="How to Use Modulation Effects Part 3: the Chorus"}}</ref> |

| The effect is based on doubling the input signal and delaying the copied signal by a certain amount of time, ranging from 5 to about 40 milliseconds. The delayed audio is then blended with the original signal and sent to the output of the effects unit. The movement effect is created by a low-frequency oscillator that constantly alters the delay time of the chorus. As it cycles its time value, it is slightly shifting the pitch of the original signal by a small amount. <ref name="techtarget1">{{cite whatis.techtarget.com|url="http://whatis.techtarget.com/definition/chorus"|title="Chorus"}}</ref> | |
