Phaser)
29: Stereo Chorus
This effect adds thickness and warmth to the sound by modulat-
ing the delay time of the input signal. You can add spread to the
sound by offsetting the phase of the left and right LFOs from
each other.
d: L Pre Delay [msec]
d: R Pre Delay [msec]
Setting the left and right delay time individually allows you to
control the stereo image.
30: Classic Chorus
This models a famous chorus unit that was built into a guitar
amp. Although it does not provide a chorus and vibrato select
switch, you can use the “Wet/Dry” and “Bus” settings to produce
their effect. The “Speed,” “Depth,” and “Manual” parameters
allow an even wider range of sounds than the original unit.
Wet/Dry
Output Mode
For the master effects, “Wet/Dry” adjusts the output level of the
effect sound.
When “Output Mode” is Mono, L and R will output the same
vibrato effect. Normally, you’ll produce a chorus effect by adjust-
ing the return level to mix the processed sound with the direct
sound. If you turn “Bus” Off and adjust the settings so that none
of the direct sound is mixed in, a vibrato effect will be produced.
If “Output Mode” is ST (L-D&R-W), the direct sound will be
panned to L, and the effect sound will be panned to R for output.
Normally, you’ll mix the direct sound and effect sound by
adjusting the return level, applying chorus only to the R channel,
and producing a stereo effect that’s spread to the left and right. If
you turn “Bus” Off, pan the direct sound and effect sound to the
left and right, and output them from stereo speakers, the effect
sound and direct sound will be panned in stereo, producing a
clear and spacious chorus effect.
