Where can I get 2-3 feet power cables to go from my amps and effects to my power conditioner? I hate the rolls of extra cable that is in my rack and need to clean it up. I only have a six space rack(full) and I have about 30 feet of power cable(combined) that I have rolled up. The regular 3 prong style(female-male). I have altered the wall-warts and taken care of those.
