So here's the deal. I was at a gig jamming right along when my bass suddenly got quiet, i turn and look back and my rack has fallen to the ground. I only managed to mess up a cable, and scratch the edges of the case. So, what i need to know is how to prevent this from happening again, outside of setting it on the ground. Alright, both my cabs are covered in carpet, my rack is 6u and goes in order; amp,tuner, power conditioner, open, wireless.
