Hey there,
I have a "marshall supervibe" chorus pedal and whenever I switch it on it hums like a bi*ch. It only hums when I use my power supply, its fine when I use batteries. Only the chorus hums, the rest of my pedals are fine with the same power supply. Any advice on what the cause if the hum is? thanks.
