Overview

Echo-Fix-EF-P3-Chorus-Vibrato-fig-1

  1. 9V DC POWER – use a clean power supply to provide the pedal with +9V DC, 200mA, centre negative power.
  2. RATE – controls the speed of the chorus/vibrato effect.
  3. RESONANCE – controls the level of vibrato signal being recirculated into the BBD input.
  4. WAVESHAPE – changes the behaviour of the modulation from a smooth sine wave (counterclockwise) to a triangle wave (clockwise).
  5. DEPTH – controls how subtle (counterclockwise) or extreme (clockwise) the pitch modulation of the chorus/vibrato is.
  6. OUTPUT – 1 K
  7. INPUT – 1 M
  8. RATE INDICATORS – indicate the rate of modulation, alternating between two horizontal and two vertical LEDs in sync with the rate selected by the rate knob (2).
  9. CLIP WARNING INDICATOR – indicates when the amount of input signal is too high and could cause the BBD to distort. Reduce the signal level of the input to avoid BBL distortion.
  10. BYPASS LED – indicates when the unit is in bypass mode (LED OFF).
  11. BYPASS FOOTSWITCH – toggles the unit to and from bypass mode. The spring pedal has buffered bypass. When powered on, the unit will be in bypass mode by default.
  12. DIRECT ON / OFF FOOTSWITCH – toggles the direct signal on and off from the output mix. With the direct signal removed from the mix, the pedal produces a vibrato effect.
  13. DIRECT ON / OFF LED – indicates if the direct signal is turned off (LED OFF) or on (LED ON).
