I had been using the two rack units @ practices and everything was fine. We had a show coming up and I needed to buy a rack in which to put them. Obviously, since it's expensive tube equipment, I bought an SKB 8U shockmount rack because I also has some other stuff to go in it. Took my rack to it's 1st venue and was a small place with not much room anywhere. Obviously, an 8 space rack sets low to the ground, making it impossible to reach controls easily during a song, so I had to set it on something. There was nothing around to set it, so reluctantly (with the convincing of my rookie guitar-tech-in-training), I set it on my 4 x 12 cab. Now it was where I could reach it, but the rack was much deeper than the cab. I tested it, moved it, tested it again and it felt steady. We had a 9 song set that night. Halfway through the last song, my whole rack comes toppling off the cab (apparently due to prolonged vibrations), hits me in the back (remember the small stage?) and crashes face-down into the floor behind me. By the grace of God, I kept right on playing the rest of the song as though nothing at all happened. In fact, I was all the more energectic to spite the nightmarish situation. The sound just kept coming out. Guess the Randall had the same philosophy as I: "The show must go on!" Anyway, the front panels were fine because of those metal, C or D shaped bars at either end of the panel. The problem is that my 1/4" plug protruded beyond this protection point and was shoved into the front input jack. The plastic nut on the front of the metal panel broke away and was forced around the plug, which peeled back the rubber sheathing on the cable. The plastic threaded input jack was ripped out of the nut and the threads were stripped off and now the jack is dangling inside the RM4. Unfortunately, the manual channel switch is somehow connected and also now dangles inside, randomly switching channels if moved around.
Now you can understand why I am so embarrased. But I actually feel like this was a harmless accident, not due to mistreatment or anything like that. Can someone please help me?
