A Closer Look at the Chrome Tone Chorus
The Chorus effect is the modulation a set of delay lines to create a more spatial or sonically rich sound. This effect is
common in guitar and keyboards, and a variety of other instruments.
The Chrome Tone Chorus uses the same Dynamic and Auto sections found in the Wah conguration to modulate the
gain in its tremolo circuit. For a detailed description of the Dynamic and Auto sections, refer to the ‘Closer Look at the
Chrome Tone Wah’ portion of this manual.
Chorus Section
The Chrome Tone Tremolo section ve
controls to adjust the Chorus effect.
• Chorus Type - selects between Flange,
Chorus 1, and Chorus 2 modes. In the
Stack conguration, an Analog Delay
mode is also available for up to 1 second
of analog delay.
• Delay - the total delay line lengths used
to create the delay modulated effect.
• Feedback - the amount of delayed signal
feed back into the input of the delay line/s.
• Mix - the balance between the dry (un-delayed) and wet (delayed) signals.
• Range - the overall modulation range from both the Dynamic and Auto sections.
Flange, Chorus, and Vibrato Effects
The Chrome Tone Chorus conguration is capable of many types of effects, including anging, slapback echo, doubling,
vibrato, and chorus. Some of these effects are detailed below.
• Flange - select the Flange mode, and dial up a Feedback value between 20 and 70. Using a delay length between
5 and 10, a signicant ange effect is heard as the Auto section is enabled, and the Depth control is set to a value
between 25 and 50. Note how using a positive or negative feedback changes the color of the ange effect (most
ange effects only offer one polarity of feedback - Chrome Tone gives both!).
• Chorus - using the Chorus 1 or 2 modes, along with all the parameters as described in the ‘Flange’ section above,
audition the effect on some tracks. Note how using the Spread control in a Mono to Stereo or Stereo conguration
increases the overall stereophonic effect of the chorus. Switching from Chorus 1 and 2 with the remaining settings
xed allows the user to get acquainted with the types of sounds these modes produce.
• Vibrato - using the same settings as in the ‘Flange’ section above, move the Mix control to 100 so only the output of
the modulated delay line is heard. Because there is no un-delayed signal in the output mix, the sound appears to
only change in pitch, creating a vibrato effect.
Chorus Modulation from Dynamic Section
Often the best chorus or ange effect is one who’s sound is NOT periodic - that is to say the modulation of the delay
line and thickening of the sound is audible, but not a repeating pattern. Using the Dynamic section of the Chorus
conguration can create great ange and chorus effects using the input audio as the modulation source. Combining
this technique with a small amount of modulation from the Auto section can create very realistic voice doubling and
multi-player effects.
