I bought an SKB roto rack case (4 space) for my Ampeg SVP pro and QSC USA-850. The designer at SKB who put the little plastic things from the edges and top and bottom of the back pertruding into the middle space was a pure genious! Now my power cable is extremely quashed and is at a horrible angle, I HAVE to use L cables to connect to my preamp, and if I want to use the XLR out, I'm screwed. Great job SKB, your engineers are geniouses!!! PS Would it really hurt to have two handles?
