Setup

- Power Connection: Connect a standard 9V DC center-negative power adapter (not included) to the "DC9V" input jack located on the rear of the pedal.
- Input Connection: Connect your guitar or other instrument to the "IN" jack on the rear of the pedal using a standard 1/4-inch instrument cable.
- Output Connection: Connect the "OUT" jack on the front of the pedal to your amplifier or other effects pedals using a standard 1/4-inch instrument cable.
- Power On: Ensure all connections are secure, then switch the "OFF/ON" toggle on the rear of the pedal to the "ON" position.
Operating Instructions
Switching Between Wah and Volume Modes
The CP-520 pedal features two operational modes: Volume and Wah. An LED indicator shows the current mode.
- Volume Mode: When the red LED light is illuminated, the pedal functions as a volume control. Rocking the pedal forward increases volume, and rocking it back decreases volume.
- Wah Mode: To activate the wah effect, firmly press down on the toe-end of the pedal until the green LED light illuminates. In this mode, rocking the pedal back and forth will produce the classic wah effect.
- Switching Back: To return to volume mode, firmly press down on the toe-end of the pedal again until the red LED light illuminates.
Adjusting Volume
The "VOL +/-" dial located on the side of the pedal allows for fine-tuning of the overall output volume. Adjust this dial to achieve your desired signal level, whether in Volume or Wah mode.
True Bypass
The pedal incorporates true bypass circuitry. When the pedal is switched off (OFF/ON toggle in OFF position), your instrument's signal will pass through the pedal without any coloration or degradation, preserving your original tone.
Maintenance
Proper care will extend the life of your pedal.
- Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Avoid using abrasive cleaners, solvents, or excessive moisture, which can damage the finish or internal components.
- Storage: Store the pedal in a dry environment, away from extreme temperatures, high humidity, and direct sunlight, when not in use.
- Power: Always disconnect the power adapter when the pedal is not in use for extended periods to prevent unnecessary power consumption and potential damage.
Troubleshooting
If you encounter any issues, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound | Incorrect power connection, faulty cables, pedal off. | Ensure a 9V DC center-negative adapter is connected and working. Check all instrument cables for damage. Verify the "OFF/ON" switch is in the "ON" position. |
| Wah Effect Not Engaging | Pedal is in Volume mode. | Firmly press down on the toe-end of the pedal until the green LED illuminates, indicating Wah mode. |
| Volume Not Changing | Pedal is in Wah mode, "VOL +/-" dial setting. | Ensure the pedal is in Volume mode (red LED). Adjust the "VOL +/-" dial to your desired level. |
