The cable (and circuit breaker) work well.  It is convenient being able to mute at the instrument when I can't reach the board.  I had originally planned to buy a 20 footer, but it dawned on me that with a 10 footer and a coupler, I could make it as long as I wanted or needed.  So, I use a regular cable to the board and then couple the 10 footer to get the circuit breaker to my position...works great and is very versatile.
