Maintenance

Keep the unit clean and free from dust. Avoid using abrasive cleaners. Store in a dry environment away from direct sunlight and extreme temperatures. Ensure all connections are secure before operation.

Troubleshooting

• Erratic behavior or popping noise: Ensure you are using the supplied AC adapter or a compatible 9VDC power supply providing at least 100mA. Third-party power supplies with insufficient current can cause these issues.
• Improper tracking: Try plugging your instrument's output directly into the B9's input. If problems persist, try using the neck pickup of your guitar and ensure your volume and tone knobs are set to maximum.
