not to correct but most pedal analog chorus is not true stereo. ce2 was just mono and pretty sure (depending on version) the cs9 is too. the dod versions that use the mn3007 chip were sold as stereo chrous but really just have a dry out as with most pedal chrous. I thought that in the priceton and peavey classic chorus amps they were actually flipping the phase of the chorus and getting true stereo chorus but I could be wrong on that.
Either way... I have tried a lot of chorus both digital and analog... from sad512 based eh memory man to dod performer 512 based, dod performer mn3007 based, ce2, dimension c, ce2b, cs9, eh small clone, ada mp1/2, mxr micro... etc. analog chorus is a whole nutha animal in that it's dirty(beautiful) and lots of warble... the princeton/peavey of that era is very clean and while I've not seen the circuit - I'd be really surprised if it wasn't digital.
all probably more than anybody cares about!
