You're looking for a source more privileged than someone from the EH design team...? My own recollection is that several of the chorus-type units were the same except for the external graphics (this was from a Guitar Shop interview with Mike Matthews). I'm sure you can find people who hear an audible difference in Microsynths (or any gear) of the same model. And then there's Eric Johnson, now claiming he hears a difference in his Fuzz Face if he secures the bottom plate with a rubber band instead of a screw.
