I am using these colour rings for my guitar cables. I have 4 cables going from my pedalboard to the amp (2 for FX loop, one for the main Input and one for the Footswitch) so it is a lot easier for me to keep them together in a flex hose, but the nightmare is which is what. This is when these colour rings save the day. They can not fall off the plug, very easy to see in the dark and great colour.
