Can anyone explain why or what this, I believe is a resistor is for, in my 120 Goodrich Volume pedal? I was changing the Pot and noticed this for the first time. Or perhaps I forgot it before. It is between the tip lugs of the output jacks. Tom Bradshaw says that this is unusual.

| I'd guess it's an isolation resistor, probably put between the two jacks to help prevent impedance interactions between two devices (e.g., with a tuner and an amp). Amplifiers have the same type of isolation resistor setup when there's two jacks going into one preamp (channel). It helps prevent a guitar or mike plugged into one channel from affecting another guitar or mike plugged into the same channel. |

Jonathan,
looks like you got a zero Ohm resistor there.
Which means it is the same as a piece of wire.
It is often used for automated PCB populating, since a machine can handle it just like other resistors (no reprogramming) and better than bare wire.
Guess it was just in reach when someone wanted to link the jacks.
Here´s one:

Thanks much, that sounds reasonable.

I've got a very old Model 120 and it has a piece of plain, uninsulated wire soldered across those two points.
