I’m getting noise when powering up my pedal through the USB port

Since the USB port on certain desktop devices are not made for audio devices and the main board might generate noise through the USB port, sometimes you will get noisy signal when powering up the pedal with USB port. You can combat this by powering up the pedal with an isolated 9V power supply or by using a proper USB power adapter. This is crucial when you need a clean signal for recording or live performance.
