5.2.6. Chorus pedal
Chorus works by adding additional delayed voices to the signal whose pitches are slightly
(or drastically!) changed over time. If you "solo" the chorus voices by turning MIX all the
way clockwise, what you will hear is the pitch going sharp and flat according to the
rate: essentially, a vibrato with adjustable rate and depth. When these pitch-altered voices
are mixed back in with the original signal it creates beat frequencies, making the sound
harmonically richer and adding a sense of movement. The chorus voices may also have a
perceptible delay, like singers slightly out of sync with each other (e.g., voice doubling). The
controls are:
Control
Description
RATE
Controls the basic speed of the chorus effect's LFO (low-frequency oscillator).
DELAY
Controls the starting delay from 0 to 25 milliseconds. In combination with the AMOUNT control,
this determines the out-of-tune range of the chorus voices.
AMOUNT
Controls how much of the RATE is applied to the DELAY time, essentially LFO depth.
MIX
Sets the balance between the "dry" original signal and the chorused voices. At full counter-
clockwise, there is no chorus signal at the output; at full clockwise, only the pitch-shifted chorus
voices can be heard (and there will be no beat frequencies).
ST.RATE
Controls the speed of the stereo chorus voices relative to the basic speed. At full counter-
clockwise, the stereo voices are basically in sync; at higher settings the left and right voices are
going at different rates.
ST.WIDTH
Sets the width of the stereo field from mono to full stereo.
The stereo effect is lessened if the
Amp is on.
TYPE
Sets the number of chorus voices and how they interact. Type 1 is a stereo voice that varies in
pitch, Type 2 adds another, and Type 3 is the most complex set of voices.
