Same as Polychorus. Kurt had two of them apparently, and used them on the Unplugged show. However, I don't know what songs he used it on. I don't think he used it one any songs, but Guitar World says that he was arguing with MTV techs over the various qualities of the Echoflangers.
THE FORGOTTEN MARINES OF TARAWA. During late-November 1943 one of the most savage battles in the history of the Marine Corps took place on the tiny island of Betio, located in Tarawa Atoll. The capture of this island took three days and cost the lives of 990 Marines and Navy Corpsmen. In addition to these, another 2,200 were wounded.
The city of Tarawa is less than 9.8 feet (3 meters) above sea level. Kiribati's president has alerted the United Nations to the challenges the country faces from beach erosion, sea-level rise, and contamination of freshwater.Rising sea surface temperatures pose an additional danger to Kiribati.owever, from 1993 to 2003 the average rate of sea-level rise increased to around 0.12 inches (3.1 millimeters) per year. With most of its land only a few feet above sea level, Kiribati has already seen growing damage from storms and flooding.
