Obviously the cable going to the footswitch is acting as an antenna for a circuit element that is now acting as a receiver.


This could caused by an open capacitor, screwy transistor or diode or a missing ground connection.


Try inserting a regular RCA phono Hi-Fi cable then short the unused end (so the center pin is shorted to the outside ring. Does this also have radio audio or does shorting the cable make it disappear?


I would look for possible broken or cracked components and solder joints in the area immediately before and after the Tremelo circuits (as a start).
