Reviewing a cable may seem strange but without them we would be stuck. The importance of this cable is increased purely because of its colour, it's so easy to get confused with a complicated patch but when you have various coloured cables the whole process becomes much easier to follow. Having various lengths of cables increases as your modular system expands and, in many cases, a long cable like this one is required more often than not. These are not an expensive bit of equipment so I plan to buy lots of each colour and then decide which should represent various functions, for example red for the audio path.
