Maintenance

- Store the amplifier in a dry place away from direct sunlight and extreme temperatures.

- Ensure all cables are properly connected and disconnected to prevent damage to the ports.
Troubleshooting
- No Sound: Ensure the amplifier is powered on, the volume is turned up, and your guitar is properly connected. Check guitar volume and cable integrity.
- Noise on Drive Channel: A slight background hiss is normal due to the nature of drive circuits. To minimize noise, avoid using the amp at low battery levels or while it is charging, as unstable power supply can make the hiss more noticeable.
- Bluetooth Connection Issues: Ensure the amplifier is within range of your device and not connected to another device. Try restarting both the amplifier and your Bluetooth device.
- Low Volume: Check the master volume (OFF/POWER VOL) and the volume on your guitar. If using AUX IN, check the AUX VOL knob and the volume on your external device.
