| Sooooo I had a CE2(Japan) sounded reeeally good. Japan made CE3 comments? Has stereo feature, two modes. Sound anything like the CE2 or is it something different entirely. |

| I have both. The CE-2 sounds warmer, but the CE-3 has stereo outs. |

| I also have both, The CE-2 does sound warmer, but not by much. the only thing I find different is the stereo outs. I use the CE-2 out front of my preamp, and the CE-3 in my EFX loop so i can take full advantage of the stereo outs. |

| The CE-3 doesn't sound like the CE-2 but in my opinion it doesn't sound bad. For some reason the CE-3 isn't very popular so it comes dirt cheap. |

I hear a difference, the CE-3 is a little more shimmery and the rate control goes farther than the CE-2. That and the stereo outs are about it. I can get my CE-3 to sound exactly like my CE-2 though. |

Today I found a mint MIJ CE-3 in my local music store and just had to buy it. After some time examining my new blue box I can say that the CE-3 is a completely diffrent thing than the CE-2. Sure both are chorus units and therfore have a lot in common but electronicaly AND soundwise there are some significant differences.
The basic character of the modulation of the CE-3 is somewhat harder compared to the very smooth waveform of the CE-2. I agree with Arcanon1313 who said it has a little more shimmery but I find the rate and depth almost identical on both units.
The biggest difference is the stereo option with its two modes on the CE-3. In mode I you get a stereo out with both channals 180 degrees out of phase (pay attention if you mix them down to mono since the chorus will be canceled out). So if you use one output only you have a normal monural chorus simmiliar to the CE-2. Mode II has the dry signal on output B and the effect signal on output A. To me it sounds like there is no original signal present in the effect output (A) so it sounds completey diffrent if you only use this output in mode II against mode I (understand? - hope my English is good enough to get things clear). It sounds more like a vibrato - very cool.
For us electronic maniacs here: A look on the pcb shows two JRC4558 (against one in the CE-2) and different BBDs. In the CE-2 a 3007 and a 3101 are working in the CE-3 I found a 3207 and a 3102. The op-amp for the modulation is the same old TL 022 in both chorusses.
Hope that helps a little in deciding wich one to get but I think it makes sense to have both since to me they are different enough to keep them both.
If anyone here has a the CE-3 service notes I would be very greatfull if I could get them. |

In addition to my post above here are two photographs of the actual modulation waveforms of the LFOs in the CE-2 and the CE-3. I think this makes clear why the CE-3 sound less smooth

Please read on in this thread! There are some corrections to this post below  |

| What points on the PCB did you put your probe for those 2 pics? |

| You get the modulation waveform if you check pin 1 of the modulation op-amp with the oscillator probe. In the CE-2 and CE-3 its the TL022 op-amp in both cases hidden under a large ceramic cap sometimes even glued together! |

| That's interesting. Does the oscillator look different between the 2 pedals or is it just component values that has changed? |

On the CE-3, they swapped the op-amps. The output of the LFO is pin 1 on the CE-2, but it is pin 7 on the CE-3. The 1st opamp will give you a square wave, the second gives the sawtooth. Check it both with the DC and the ac inputs on your scope. The LFO circuit will not drive a load, which is why the transistor buffer follows it. I've noticed that the ac in on a scope will load that enough to change the waveform. Your CE-3 would be a VERY bad sounding chorus if it had a square wave modualting the clock frequency. 
Grace and peace,
Steve

quote: but it is pin 7 on the CE-3
Hmm...maybe I was a little to fast with my conclusion about the waveform 
I checked my CE-3 once again at pin 7 and it has almost an identical waveform like the CE-2 Sorry about the wrong information!
But it seemed so logical since I find the sweeping of the CE-3 a lot less smooth than the one of the CE-2. It is more like stepping up and down than fading in and out if you know what I mean.
The hint with the ac/dc inputs is very usefull too. Thanks phostenix!

I'm just about certain that any attempt at Portugese on my part would be far worse. Far too easy to take the first language for granted when its English...
I hope that someone here has access to the schematic and service information -- I checked all of my sources and couldn't find it.
C.K.
