  • REGEN: Controls the effect strength or feedback. Adjusting this knob changes the intensity of the flanger effect.
  • DELAY TIME: Adjusts the effect frequency. This knob controls the delay time of the modulated signal, ranging from 0.9ms to 6.4ms.
  • WIDTH: Determines the effect depth. This knob controls the sweep range of the flanger effect.
  • SPEED: Controls the effect speed. This knob adjusts the rate of the flanger's modulation, with a speed range of 0.4Hz to 8Hz.
  • FOOTSWITCH: Engages or disengages the effect. When the effect is disengaged, the pedal operates in true bypass mode.

3. Setup

Proper setup is crucial for optimal performance and to avoid unwanted noise. Follow these steps to connect your JOYO Classic Flanger pedal.

  1. Connect your guitar to the INPUT Jack (1/4-inch mono) on the right side of the pedal.
  2. Connect the OUTPUT Jack (1/4-inch mono) on the left side of the pedal to your amplifier or the next pedal in your signal chain.
  3. Ensure all connections are secure before applying power.

  • The pedal requires a DC 9V power supply with a 500mA current rating and a center-negative polarity. The included adapter meets these specifications.
  • Connect the DC 9V power adapter to the DC 9V input jack on the top of the pedal.
  • The pedal can also be powered by a 6F22 battery (not included).
  • The LED Indicator will illuminate when the pedal is powered and the effect is active.

4. Operation

Once the pedal is connected and powered, you can begin to explore its flanger effects. Use the control knobs to shape your sound.

  1. Turn on your amplifier and guitar.
  2. Press the footswitch to engage the flanger effect. The LED indicator will light up.
  3. Adjust the REGEN knob to control the intensity of the flanger sweep. Higher settings create a more pronounced, resonant effect.
  4. Adjust the DELAY TIME knob to change the fundamental frequency of the flanger. This can shift the character from subtle to more pronounced.
  5. Adjust the WIDTH knob to control the depth of the flanger's sweep. Lower settings result in a shallower, more subtle effect, while higher settings create a deeper, more dramatic sweep.
  6. Adjust the SPEED knob to control how fast the flanger effect modulates. Slower speeds create a gentle, swirling effect, while faster speeds can produce rapid tremulous vibratos.
  7. Experiment with different combinations of these controls to achieve a wide range of flanger, chorus-like, and vibrato sounds.
  8. Press the footswitch again to disengage the effect. The LED indicator will turn off, and the pedal will operate in true bypass mode.
