[QUOTE="kc2eeb, post: 100188, member: 811"] Make sure the series and parallel loop jacks are functioning properly. Connect the in and out jacks with a patch cord. If that fixes it then the jack shorting switches need cleaning. Make sure the volume pot shaft hasn't taken a hit and unseated it's back cover. Pull the knob and see if the pot shaft is stable and not wobbly. If you pull out on it you should feel a small movement out with spring tension on it. The tension is from the wiper. You should not be able to feel any movement when you push in on the shaft. The pot's back cover holds the shaft in proper position and tensions the wiper on the trace. [/QUOTE]
