Hearing hissing, hum or any low level noise is common when the gain is turned up on a pedal or the amp. An individual frequency component of the complex wave having it’s phase is shifted by 180° would convert a negative feedback amplifier into a positive feedback amplifier at particular frequencies and cause severe instability. Choosing the right RFI noise filter or suppressor can play a very important part in reducing your RF interference. i only experience this when i use effects (chorus, delay, equalizer). If the noise stops, connect them back to the receiver or processor on at a time until the noise returns.
