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.
Since 1968 the name Tara is currently accepted as being exclusively a female name in Western societies, although there have been men who carried the name (such as Tara Browne). It is also often considered a female name in the east, due to its connection to several goddesses. For instance, Tara is a female Buddha in Buddhism and a goddess in Hinduism. Additionally, Tara is also a common male or female name meaning star.
