Chorus

Chorus: Chorus pedals mimic the effect choirs and string orchestras produce naturally, by having slight variations in timbre and pitch, by mixing sounds with slight differences in timbre and pitch. A chorus effect splits the instrument-to-amplifier audio signal, and adds a slight delay and frequency variations or vibrato to part of the signal while leaving the rest unaltered.[74][75] A well-known usage of chorus is the lead guitar in "Come As You Are" by Nirvana.[63]
