5. Operating Instructions
Engaging/Disengaging Effects:
Press the footswitch (7) to toggle the effect on or off. When the effect is active, the LED indicator will illuminate. When off, the pedal operates in true bypass mode, allowing your signal to pass through unaffected.
Selecting Effects:
Rotate the Effect Selector Knob (2) to choose from the 16 available effects. The selected effect will be active when the pedal is engaged.
- Delay Effects: Delay 1, Delay 2, Echo
- Reverb Effects: Stadium, Church, Hall, Room 1, Room 2
- Modulation Effects: Mod Tone, Chorus, Wah, Flanger, Tremolo
- Distortion/Special Effects: Metal, Sur 1, Sur 2
Adjusting Effect Parameters:
Use the MIX, TONE, and DECAY knobs to fine-tune the selected effect:
- MIX Knob (3): Turn clockwise to increase the amount of effect blended with your dry signal. Turn counter-clockwise to reduce the effect.
- TONE Knob (4): Adjusts the brightness or darkness of the effect. Experiment to find the desired character.
- DECAY Knob (5): Controls the duration or sustain of the effect. For delays, this might control feedback; for reverbs, it controls the reverb tail length.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound when pedal is engaged. | Incorrect power supply; faulty cables; pedal not receiving signal. | Ensure 9V DC (center negative) power supply is connected. Check all instrument cables for proper connection and functionality. Verify guitar and amplifier are working. |
| Effect is too subtle or too dominant. | MIX knob setting is incorrect. | Adjust the MIX knob (3) to achieve the desired blend of dry and wet signals. |
| Unwanted noise or hum. | Ground loop; interference from other electronics; faulty power supply. | Use a high-quality, isolated power supply. Ensure all cables are properly shielded. Try moving the pedal away from other electronic devices. |
| LED indicator not lighting up. | No power; faulty LED. | Check power supply connection. If power is confirmed, contact customer support. |
