It's less about saving time than it is the inconvenience of getting around to the back of the heads in the tight space of my studio. There's plenty of room for the amps to breath. However getting behind them means moving a few things. Not a big deal but it would be a convenient to be able to switch them if there is a way to do it safely. I can remember to power down an amp before I switch.
Cool, thanks. Serious question for the pizza eaters: Can you see any reason why this solution would be a bad idea?
You know how inconvenient a blown amp is?
It isn't inconvenience, it is lazy.
