A chorus pedal is a great way to create thicker sounds from a single signal. By taking your source signal, doubling it and setting the second signal slightly out of tune and time with the first, a chorus pedal can create the sound of two instruments playing simultaneously. Depending on how you set the oscillation rate and depth, or intensity, of the effect, you can create sounds that range from shimmering rotary-speaker-like textures to deep watery warbles.
Chorus has been a favorite effect of guitarists for years, and in this video, “Three Things You Need to Know About Chorus Pedals,” Phillip McKnight explores the pedal in depth. He talks about what chorus is, why you’d want to use it and how to use it. (Side note: There are a couple of times in his explanation when Phillip describes two vocalists singing in harmony, when he actually means in unison—singing the same note together rather than harmonizing.)
