Why is there a squeal or hum noise when using BIAS Pedal Distortion?

The squeal sound is likely caused by ground loop. With multiple devices connected in your signal path, the voltage difference between the ground terminals of each device will cause the current to flow between devices and generate noise. To avoid this noise, remove the device one by one from the original power source and see which one is causing the noise. Once you pinpoint the source of the noise, connect that device with other another power source or battery.
