6. Troubleshooting
- No Sound:

- Check that your headphones are securely plugged into the 1/8-inch jack.

- Confirm your guitar is properly connected and its volume is turned up.
- Bluetooth Connection Issues:
- Ensure the Mustang Micro is in Bluetooth pairing mode (flashing blue LED).
- Check your device's Bluetooth settings and ensure it's searching for new devices.
- Try unpairing and re-pairing the device.
- Recording Problems via USB:
- Ensure the USB-C cable is securely connected to both the Mustang Micro and your computer.
- Verify that your DAW recognizes the Mustang Micro as an audio input device.
- Check input levels within your DAW.
- Short USB Cable for Interface Use: The included USB-C cable is short, primarily for charging. If using the Mustang Micro as an audio interface with a computer, you may need a longer USB-C to USB-A or USB-C to USB-C cable, depending on your computer's ports.
