A big western howdy, I once ran sound for a country/western band. At one point the girl singer would hold a high note for some time. I would be ready with my ibanez fine delay control full up. When she hit the note, i'd send it to the delay and slowly turn the knob down(longer delay time). It also sounded like it'd never stop. Until i got to the end of the control knob range of course.
