phaser

[Goddard, Duncan]

you'll get some phaser-like effects using delay lines, because of
comb-filtering, but it's not the same thing at all as a swept notch filter,
which is what phasers really are. flangers and choruses are much closer
relatives, using the same delay line technique but with different modulation
depths and so on.
