I am not happy with my present guitar cord(s). They keep getting twisted up as I move around. Is anyone familiar with the Vintage Voltage cords (I think that is the name) sold by Fender. Price looks reasonable for a tweed like covered cord which I think would not twist up as much as rubber or vinyl or whatever most cords seem to be made from on the outside. Also is there anything to the oxygen free concept in cords or is that just some marketing gimmick?
