I'm wondering if anyone could hip me to a certain pedal/effect I heard Kurt use over "Spirit Kiss" at the Village Vanguard this past week. It takes every note he strikes and harmonizes that tone with a higher one -- when I heard Kurt use it, it harmonized his playing with either a fifth an octave higher, or some other interval (I think it was an octave or something close, but I can't remember).
Also, there is another he used on "Bass Place" that would allow him to form and sustain a chord constantly so that he could then play over it. Any ideas?
I'm a complete gear neophyte, so any input would be greatly appreciated.
