This bit of kit is very usefull. It connects all the on stage amps, mics, etc into an easy to use bundle of cables. The mixing desk then connects from each cable, and we have a great sound balance. We can also run a return cable through the snake, to feed an onstage monitor. It all helps to give us a great sound , both front of house, and , as importantly, on stage, where we can hear the drums, bass etc. It comes on a handy little reel, and is so easy to use.
