I had an idea on the way back from a gig. I dunno, maybe this has been done before. Knowing my luck it probably has. Don't you hate it when the prongs on power cables get bent? The one on my expensive amp is always getting bent because it's around other heavy equipment. I bend it back, but I know when you bend it back the metal weakens, and it will eventually break off. So, what if there were little plastic blocks that you could slide the power cable end into when you're not using it? Just something to keep it from getting bent. It's been done before, right?
