I’ve noticed a high pitched noise coming from my guitar amp when I’m not playing. It’s coming from the Voice Box. When I scroll through the presets there is a change to the noise. This happens with the pedal even if the pedal is off.
Indeed, but now that I’m thinking about it I have that power supply powering two other pedals.
Do you think this might be the issue?
Very possible. I’d try unplugging the others and see if the noise goes away. I wouldn’t recommend powering additional pedals w/ the Voice Box’s original power supply. I’m not sure how much current it requires but adding a couple more pedals might be stretching it.
