I happened to see a 20' roll of this at big lots of all places, for only 8 bucks, so I picked it up because I wanted to make an extension cable, going 1/8 stereo female to 1/8 stereo male. This cable is "star quad" configuration and I was wondering how to wire it. this cable has the bare ground, and two blue wires and two white wires, along with the shielding, etc... for some reason I though star quad cabling was only for XLR. any guidance? Im looking for which wires go to tip, ring, etc..
