Info on Stereo Chorus (rack) effect

  • Does anyone know what real-world hardware is modeled by the effect entitled "Stereo Chorus"? It's the rack-mounted one with the orange front panel. I'm trying to understand what all the controls do, and I figure one good place to look is a manual for the hardware this thing is modeling. (Since, ahem, PG doesn't provide any info AT ALL about how to use this effect.) For example each side has a delay knob, but my ears don't hear anything like a delay when I tweak these knobs. Likewise, what exactly do the "number of voice" knobs do?
