Check the tank transducers with an ohmmeter. Both input and output coils will normally have around 180-200 ohms dc resistance. Sometimes you just can't see the damage. If there is no noise from shaking the tank, then the output transducer or return circuit or wiring is suspect. If you pull out the RCA plug from the output side of the tank, you can touch the tip of the plug and see if there is a buzz.

Almost all Kustom amps use switching transistor circuits to turn on and off the FX, so there is no audio signal carried on any of the footswitch cables. It could be possible that the trem circuit is putting a pulse into power supply. Maybe a bad cap.
