The guys from the Pres. of the United States of America actually got the idea (and their first 2 string btw) from Mark Sandman of Morphine. Mark used several diferent instruments, I think some were basses w/ 2 strings, and some were guitars w/ 3. He also used regular guitars, keys, and other weird things for his various songs. Anyway, it sounds like Cahtz is almost trying to do a Charlie Hunter (who is awesome in my humble opinion). Whatever you do, good luck, just remember that having low tension on one side of the neck and normal tension on the other is just as bad as way too high tension all the way across.
