CE-1 Chorus Ensemble
The chorus circuit out of a Roland amplifier, put on the floor.
A delay that will not sit still
A short delay is modulated so its time wanders, then mixed back against the dry signal. A moving delay is a moving pitch, so the two drift in and out of tune with each other, and the beating between them is the effect.

What the circuit does
A bucket-brigade delay line, modulated by a low-frequency oscillator so the delay time wanders, mixed back against the untouched dry signal. A moving delay is a moving pitch, so what you hear is the wobbling copy beating against the steady original.
What to listen for
Two of you, slightly out of tune with each other, rather than an effect sitting on top of one of you. The vibrato mode drops the dry signal entirely, at which point the pitch movement stops being a shimmer and becomes the whole sound.
Where it goes
The modulation slot
After the gain and before the delay, so the delay repeats a modulated signal rather than modulating an already repeated one. Reversed, the movement gets applied to the echoes as a block and the effect smears instead of swirling.
