The 2 Button Footswithch, 4 Button Footswitch, and EXP-1 Expression & Volume Pedal units that work with the Mustang III/IV/V come with twin conductor zip cord style 10" cables prefitted with 1/4 Phone plugs. These cables are not shielded.

If your application requires runs substantially longer than the 10" included cables, the use of shielded cables or Snap on ferrite choke beads at each end would be a good idea to prevent spurious RFI from getting in the line.
