Maintenance
To ensure the longevity and optimal performance of your Lester-G pedal, keep it clean and free from dust and moisture. Use a soft, dry cloth for cleaning. Avoid using abrasive cleaners or solvents. Always use the specified 9.6V DC power supply to prevent damage to the unit.
Troubleshooting
- No Sound: Check all cable connections, ensure the power supply is correctly connected and functioning, and verify that the pedal is not in bypass mode if you expect an effect.
- Unexpected Noise: Ensure all cables are in good condition and properly shielded. Try using a different power outlet or power supply to rule out electrical interference.
- Effect Not Engaging: Confirm the BYPASS footswitch is pressed to activate the effect. If using an expression pedal, ensure it is correctly connected and calibrated.
