I've done the Google search rack ears for an MB500 head. I'd really like to throw this head into a small rack case (with rack tuner and power conditioner) so that this thing isn't just dangling loose inside of a gigbag. I've found other people upset about how GK doesn't make rack ears for it, I've found a company that sells them but is out-of-stock, and I'd like to hear what your takes are on solving this issue. Has anybody cut any corners and found something make-shift without involving duct tape?
