Marshall PEDL-90016 2-Way Footswitch
The Marshall Origin series employs a logic-switched FX loop that is 'Normally Off'. Without the latching ground signal provided by the specific footswitch, the internal relay cannot energize to route the signal through the Send/Return jacks, appearing as a circuit failure to the user.

1/4" PCB-Mount Switching Jack
The FX loop utilize switching jacks with internal leaf-spring contacts (shunts). Mechanical fatigue or atmospheric oxidation on the 'Return' jack's shunt prevents the pre-amp signal from returning to the power amp stage when the loop is engaged, breaking the series signal chain.

Signal Switching Relay (12V DC DPDT)
The electromechanical relay is the physical mechanism that diverts the audio signal. Failure of the relay coil or pitting of the internal gold-plated contacts prevents the physical movement of the signal path from the internal bypass to the external loop jacks.
