This was pretty easy to do convincingly btw!
Multitap delay, quad tape delay type, all panned center, fourth tap muted, third tap set at a lower volume and with a longer feedback (25 to 45%), first and second tap volumes set to taste with the same feedback amount as each other (I liked 10 to 25%), and modulation set to be a little warbly (slower speed and higher depth) and with the astable waveshape.
Delay times are not tempo synced (important imo!), and tap 1's is set to 72ms, tap 2's is set to 155ms, and tap 3's is set to 200ms. Use motor speed to change the delay time while keeping this ratio; with the motor speed at 1.0, that's the fastest delay times on the Strymon Olivera, and with the motor speed set to 0.25, you'd be at the longest delay time on the Olivera, but adjust however.
Cool sound and really has that "reverb but not reverb" effect, especially when playing with the filter for darker sounds. The diffusion adds a lot too, but not really necessary imo
ETA: and I really recommend putting this into the front of an amp vs after btw
