Chorus is a pitch and delay effect that adds a rich, shimmering quality to a sound by detuning and delaying the incoming signal and combining it with the unaffected signal. The Ultra Chorus has a dedicated LFO which acts as a ‘LUSH’ control, giving this unit a very dense, rich character compared with other choruses.

Controls the mix of the dry signal and the processed (Wet) signal. The percentage indicated is the amount of the signal that is Wet.
Range: 0% ~ 100%


  • RATE
    This control sets the cycle speed of the LFO. Minimum settings will produces a sweeping effect, higher settings will make for a more warbling effect.
    Range: 0.00Hz ~ 15.00 Hz
    The Depth control adjusts the amount of pitch modulation from the LFO.
    Range: 0.01 ~ 0.98
    Controls the Delay time.
    Range: 0.00 ~ 1.00
    These three waveforms control the contour of the pitch change applied to the delay.
  1. Sine – A symmetrical, smoothly cycling wave.
  2. Random – Asymmetrical changes in the wave make randomized pitch changes.
  3. Linear – A symmetrical, linear cycle.
  • LUSH
    Sums the left and right signal, adding more density to the sound.


    Applied to the Delay, Feedback repeats the delays for more sonic density. At minimum settings the difference is minor, At maximum settings it creates flanging metallic overtones.
    Range: 0.01 ~ 0.98
    Reverses the phase of the chorus.
    Pans the chorused signal to left and right, widening the stereo image.
    Range: 0.00 ~ 1.00
  • TONE
    Tone is a combination high-pass and low-pass filter. When set at 12-O’Clock (.500) the Tone is neutral. When shifted clockwise, a high-pass filter is applied and when changed counter-clockwise, a low-pass filter is applied.
    Range: 0.00 ~ 1.00
    Adjusts the overall output.
    Range: -inf ~ 0.00
