I purchased a used VP JR and when I plugged it in to try it out, I couldn't get anything to come through. I tried the tuner output and the sound was able to come through the tuner output as usual, but when the normal output is used there is nothing coming through. Is this generally an issue with the inputs or with the potentiometer? I know that the tuner is wired directly from the input and does not pass through the potentiometer which is why I am unsure of whether or not to purchase a new pot or figure out something to do with inputs.
