- Room: Simulates the natural reverberation of a small to medium-sized room.
- Hall: Emulates the expansive and lush reverb of a large concert hall.
- Church: Provides a very long and resonant decay, typical of a large church or cathedral.
- Spring: Recreates the classic sound of a spring reverb tank, often found in vintage guitar amplifiers.
- Plate: Offers the smooth, dense, and bright decay characteristic of plate reverbs.
- Studio: A versatile and balanced reverb suitable for various studio applications.
- Mod: A modulated reverb, adding subtle pitch or amplitude variations to the reverb tail for a unique texture.

Adjusting Controls
Fine-tune your reverb sound using the three control knobs:
- E.LEVEL Knob: Adjusts the overall volume of the reverb effect. Turn clockwise for more effect, counter-clockwise for less.
- DECAY Knob: Controls the length of the reverb tail. Turn clockwise for longer decay times, counter-clockwise for shorter decay times.
- TONE Knob: Shapes the tonal character of the reverb. Turn clockwise for a brighter, more present reverb, and counter-clockwise for a darker, warmer sound.

Maintenance
To ensure the longevity and optimal performance of your pedal, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Do not use abrasive cleaners, solvents, or waxes, as these can damage the finish and internal components.
- Storage: Store the pedal in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. Disconnect the power adapter when not in use for extended periods.
- Handling: Avoid dropping the pedal or subjecting it to strong impacts. While the aluminum casing is durable, excessive force can cause damage.
- Power Supply: Always use a regulated DC 9V power adapter with a center-negative polarity. Using an incorrect power supply can damage the unit and void the warranty.
Troubleshooting
If you encounter issues with your Donner Verb Square pedal, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound when pedal is engaged. | Incorrect power supply; loose cable connections; faulty cables; incorrect signal chain. | Ensure a DC 9V center-negative adapter is used. Check all instrument cables are securely connected. Test with different cables. Verify the signal chain (instrument > pedal > amplifier). |
| LED indicator does not light up. | No power; faulty LED. | Check power adapter connection and ensure it's functioning. If power is confirmed and LED still doesn't light, the LED may be faulty, but the pedal might still function. |
| Reverb effect is too weak or too strong. | E.LEVEL knob setting. | Adjust the E.LEVEL knob to increase or decrease the intensity of the reverb effect. |
| Reverb tail is too short or too long. | DECAY knob setting. | Adjust the DECAY knob to control the length of the reverb tail. |
| Reverb sound is too bright or too dark. | TONE knob setting. | Adjust the TONE knob to brighten or darken the reverb sound. |
If the problem persists after trying these solutions, please contact Donner customer support.
