Ancient post and thread but... I often have guests come on my radio show with amplifiers and various sound-processor pedals. They simply DON'T play acoustically, and seem to be lost if asked to. I just go with the flow even though it seems a bit silly to have amps in a tiny studio.

“(James O.) Weldon later liked to tell horrific stories of the power of those stations. He said that at about 9:00 p.m. on a summer evening, just before full dark, if you stood near the five towers of XERA in Ciudad Acuña you could see a bluish white light glimmering from the guywires leading to each tower. The eerie glow was a corona effect outlining the framework of the structures as the transmitters pulsed out that overpowering transmission.

"And," he said, "when we were going at full power, 750,000 watts, folks over in Del Rio would call us and complain that when they turned on their fluorescent lights, they couldn't turn them off."
