I would NEVER think of transporting my gear, especially the kb without a cover ... My power amp is an old Peavey (I can't remember the model #) and when I bought it they didn't make a cover for it ... I cut the top flaps off the original shipping box, cut a slit in the bottom for the handle of the head and then got the widest black electrical tape I could find and covered the box with the tape ... Now all I do is drop the box over the head...
With the price of good gear these days, I can't imagine 'pros' especially, not taking care of it ...
Dnj .... was their performance as sloppy as the gear? ...
Starkeeper ... If you're going to keep using the kb box, you might want to think about covering it with duct tape or something similar to strengthen it, keep rain and snow off, etc. .... otherwise, once you start making some $$$ playing out , get a proper case...
