2. Setup
Follow these steps to connect your Small Stone Nano pedal:
- Power Connection: The pedal operates on a 9V battery (included) or an optional 9V DC power adapter (center negative).
- To install or replace the 9V battery, remove the four screws on the bottom plate of the pedal. Carefully lift the plate and connect the battery to the clip. Replace the bottom plate.
- For external power, connect a 9V DC power adapter to the 9V power jack located at the top of the pedal. Ensure the adapter is center negative.
- Input Connection: Connect your guitar or the output of a preceding effects pedal to the INPUT jack on the right side of the Small Stone Nano using a standard 1/4-inch instrument cable.
- Output Connection: Connect the AMP jack on the left side of the Small Stone Nano to your amplifier's input or the input of the next effects pedal in your signal chain using a standard 1/4-inch instrument cable.
3. Operation
The Small Stone Nano features simple controls for intuitive operation:
- Footswitch: This switch engages or bypasses the effect. When the effect is active, the STATUS LED will illuminate. The pedal features true bypass switching, ensuring your dry signal remains unaffected when the pedal is disengaged.
- RATE Knob: This knob controls the speed of the phase shifting effect.
- Turning the knob clockwise increases the rate of the phase sweep.
- Turning the knob counter-clockwise decreases the rate of the phase sweep.
- COLOR Switch: This two-position toggle switch alters the character of the phase effect.
- In the down position, the phase effect is more subtle and transparent.
- In the up position, the feedback is increased, resulting in a more pronounced, intense, and "tingling swirl" phase effect.
4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your pedal:
- Battery Replacement: When the STATUS LED dims or the effect weakens, it's time to replace the 9V battery. Always use a fresh alkaline 9V battery.
- Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Avoid using abrasive cleaners or solvents, as these can damage the finish and internal components.
- Storage: When not in use for extended periods, disconnect the input cable to prevent battery drain. Store the pedal in a cool, dry place away from direct sunlight and extreme temperatures.
5. Troubleshooting
If you encounter issues with your Small Stone Nano, consider the following:
- No Sound or Weak Effect:
- Check all cable connections to ensure they are secure.
- Verify the 9V battery is fresh and correctly installed, or that the power adapter is functioning and properly connected.
- Ensure your guitar and amplifier are working correctly.
- Unwanted Noise or Hiss:
- Ensure all cables are in good condition and properly shielded.
- If using an external power supply, ensure it is a regulated 9V DC center-negative adapter designed for audio pedals. Unregulated power supplies can introduce noise.
- Test the pedal in a different power outlet or with a fresh battery to rule out power supply issues.
- Some ambient electrical interference can be picked up by guitar pickups or cables; try moving away from sources of interference.
- Effect Not Engaging:
- Check the footswitch for proper operation.
- Ensure the pedal is receiving power (STATUS LED should light up when engaged).
