3. Setup
3.1 Power Supply

3.2 Connecting the Pedal

- Input Jack: Connect your instrument here.
- Output Jack: Connect to your amplifier or the next pedal in your signal chain.
4. Operating the Pedal
The Rowin Slow Hand pedal features intuitive controls for shaping your sound.

4.1 Controls
- THRESHOLD Knob: Adjusts the sensitivity of the volume swell effect. A higher threshold requires a stronger input signal to trigger the swell.
- SWELL Knob: Controls the attack time of the volume swell. Turning it clockwise increases the time it takes for the sound to reach full volume, creating a slower swell effect.
- TRUE BYPASS Footswitch: Engages or disengages the effect. When disengaged, the signal passes through the pedal without alteration. The LED indicator illuminates when the effect is active.
4.2 Modes
- Normal Mode: Allows for real-time adjustment of sound parameters using the THRESHOLD and SWELL knobs.
- Fixed Mode: Enables the storage of a set of preferred parameters, providing consistent performance. Refer to the included owner's manual for specific instructions on saving settings in Fixed Mode.
5. Maintenance
- Keep the pedal clean by wiping it with a soft, dry cloth.
- Avoid exposing the pedal to extreme temperatures, humidity, or direct sunlight.
- Do not attempt to disassemble or modify the pedal, as this will void the warranty.
- When not in use for extended periods, disconnect the power supply.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|
| No sound when pedal is engaged. | Incorrect power supply, faulty cables, pedal not receiving power. | Ensure DC 9V power supply is connected and functional. Check all cable connections. Verify the LED indicator is on when engaged. |
| Unwanted noise or hum. | Interference from other electronics, ground loop, faulty power supply. | Use a high-quality, isolated power supply. Try moving the pedal away from other electronic devices. Check cables for damage. |
| Effect is not noticeable or too subtle. | THRESHOLD or SWELL knobs set too low. | Adjust the THRESHOLD and SWELL knobs to higher settings. Experiment with different knob positions to find the desired effect. |
