Going to try and wire up Leo's board to G25 pedal pot's.
Leo recommends using shielded cable.
Unsure of how to connect the shielded cable.

Is the shield connected to pots ground or usb board ?Or both(ground loop)?
Presume connect ground cable as well as shield?

On G25 pot side ,planning on using crimped spade connectors , original size.

If usb , do you just twist excess shielding and solder to pin connector?

Not to hot with a solder iron, is there an easier way to connect to pin connectors ?

Is this suitable cable

The shielding should be grounded on both ends to the ground wire, all connections should idealy be soldered.

You could just ground to one end with the shielding if you plan on using push-on spade connectors for the pot ends of the wires, if you do that you will want the shielding to be cut so it cannot short to any leads, it needs to be back a bit from the wires it covers.

If you use the wire you have posted the link to you are going to need to ground all of the shields. The best way to do that would be to ground them to the board, through the ground wire of the pot they are connecting.

Also, those pin connectors you linked are going to have to be soldered, there's no other way to connect the wires to them. Just be realy careful and use a heat sink, you realy don't want to melt the plastic.
