ES2 integrated effects processor
ES2 is equipped with an integrated effects processor. Any changes to the parameters of these
effects are saved with each sound setting.
Click to choose a hard
or soft type of Distortion
effect.
Use the Tone parameter
to alter the tonal color of
the Distortion effect.
Adjust to set the level of
Distortion.
Click to choose Chorus,
Flanger, or Phaser effect.
Intensity and Speed
parameters are shared
by the Chorus, Flanger,
and Phaser effects.
You can activate only two effects at the same time.

Choose the Chorus, the Flanger, or the Phaser effect. These effects share the same control
knobs—Intensity and Speed.
A chorus effect is based on a delay line, the output of which is mixed with the original,
dry signal. The short delay time is modulated periodically, resulting in pitch deviations.
The modulated deviations, in conjunction with the original signal’s pitch, produce the
chorus effect.
A flanger works in a similar fashion to a chorus, but with even shorter delay times. The
output signal is fed back into the input of the delay line. This feedback results in the creation
of harmonic resonances that wander cyclically through the spectrum, giving the signal a
“metallic” sound.
A phaser mixes a delayed and an original signal. The delayed element is derived from an
allpass filter, which applies a frequency-dependent delay to the signal. This is expressed as
a phase angle. The effect is based on a comb filter, which is basically an array of inharmonic
notches—rather than resonances, as with the flanger—that also wanders through the
frequency spectrum.
