6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the amplifier's exterior. Do not use liquid cleaners or abrasive materials.
• Tube Replacement: The 12AX7 preamp tube may need replacement over time. If you experience a significant change in tone or performance, consult a qualified technician for tube replacement.
• Storage: Store the amplifier in a dry, cool place away from direct sunlight and extreme temperatures.

7. Troubleshooting

• No Sound: Ensure a speaker cabinet is properly connected to the SPEAKER OUTPUTS. The amp head does not produce sound on its own and requires an external cabinet speaker. Check all cable connections (guitar, power, speaker). Verify the amplifier is powered on and the volume/gain controls are not set to zero.
• Excessive Noise/Hum: Check for proper grounding of all equipment. Ensure all cables are in good condition. Try using a different power outlet. If using external pedals, try bypassing them to isolate the source of the noise.
• Bluetooth Connection Issues: Ensure the Bluetooth button is pressed and the indicator LED is blinking. Check that your device's Bluetooth is enabled and visible. Try restarting both the amplifier and your Bluetooth device.
