Roland Corporation RotoSound Schaller electronic Schulte Audio Elektr.The CE-1 is based on a circuit which Roland used in their JC-120. Jazz Chorus amplifiers first released in 1975?. It was the first effect pedal to utilize a BBD (Bucket Brigade Device) chip. Originally designed by Philips this IC had just been licensed to. Matsushita and thus was available for mass production. The CE-1 is a mains powered unit that features both chorus and vibrato modes. They both use the same BBD circuit so it is impossible to use bothAny hint is highly appreciated.

Check that the minimum and maximum values for the delay time are as follows. fig.check1 INPUT SET CONTROLS. The CE-2 builds on the legacy of the CE-1 with reduced features: mono output instead of stereo, no vibrato mode, no integrated power supply, no level and no intensity controls. The CE-2 has higher input impedance and boosted mid frequencies, both arrangements very suitable for electric guitars. Roland stopped marketing the CE-2 in 1982, however still produced until 1990. There are basically 3 versions of the pedal: Some early stand-alone stompboxes like Vibra-Chorus and Uni-Vibe by Shin-Ei were released in 1960s, creating some degree of phase shifting or chorus modulation. The CE-2 follows the same tonal response. The usual delay times are around 5 to 50ms and LFO oscillating frequencies are up to 20Hz. CE-2 uses triangle LFO waveforms. There are several possibilities: Hearing both signals together the chorus effect is created. The input and output circuits use the dual op-amp uPC4558C IC, while the LFO is implemented with the help of a TL022LP op-amp. Some additional active filtering is applied using Sallen-Key transistor stages. The effect response is commanded using two controls: The top of the board contains all the pads to attach the cables to be connected to the jack connectors, potentiometers, and the footswitch. It also carries other benefits like the number of components used in the pedal and using a light indicator and a power-on LED at the same time. The JFET Bypass Switch enables two possible toggle configurations: The VR 3 potentiometer is able to finely trim the 4.5 voltage: sometimes due to the loading of all stages, the 4.5 voltage might suffer some offset, the BBDs are sensitive to the bias, adjusting VR3 will bring maximum clean headroom. The 9V regulated line will bring the supply for the Bucket Brigade Stage, rejecting high-frequency harmonics which are especially harmful in BBDs signal processing due to the clocking noise of the MN3101 clock driver. This pedal was originally designed for an external 12V ACA supply adapter. The series resistor R53 and diode D5 between the minus input on the power jack and ground are used to reduce the internal voltage supply. The voltage drop over the resistor and diode will under-power the pedal making the power-on LED glow faintly. One easy solution is to use a daisy chain cable together with another standard pedal. The link between the two pedals will short the resistor-diode circuit and the pedal will receive full power. It also separates the guitar from any pedal DC potential, protecting the pickups in case of circuit failure. But applying the same filtering to the delay signal, the output signal will reduce any hiss acquired via the delay path. Boss CE-2 uses the op-amp inverting architecture. It is also implemented over the 4558 dual op-amps and designed to attenuate the magnitude of the high frequencies with respect to the mid-low frequencies. This filter takes the unnatural sounding pre-emphasized audio and turns it back into its original response. These are generated at integer multiples of the sample rate. The ideal filter specification is the same as that for the anti-aliasing filter. In this way, the input signal is bandlimited to prevent aliasing. The cut-off frequency can be calculated as: The output signal must be bandlimited, to remove the clock noise and prevent aliasing (meaning Fourier coefficients being reconstructed as low-frequency waves, not as higher frequency aliases). The cut-off frequency can be calculated as: After the delay stage, slightly more bass pass through the circuit. At the same time, a Low-Frequency Oscillator (LFO) is needed to drive the MN3101 in order to generate the variable delay time which is the gist of the chorus effect. It is used to discharge the C 22 47pF timing capacitor, which is charged through the R 38 150K resistor. Indeed, Q 5 together with the MN3101 will oscillate by itself at a constant frequency without Q 4 and its associated components. The cycle repeats at an ultrasonic rate. Immediately after C 22 discharge, the diode D1 is needed to isolate the output of Q4 transistor.As the LFO cycles, the delay time goes up and down and therefore the delayed audio pitch slightly shifts up and down. Some ticking can be mixed with the audio when the LFO produces the rising or falling edge of a square wave and there is a very sudden surge in the current. This simple circuit provides a variable frequency triangular waveform whose amplitude is also variable. The oscillation frequency can be calculated following the formula of the Triangle Oscillator by Ron Mancini: The action of VR2 will modify the steepness of the ramp and therefore the amplitude or depth at a fixed frequency.

It did work but I decided to recap it. Yep you guessed it, now it has a problem. The chorus still works fine. The vibrato only works for about a second before the oscillation stops. I still have sound. When engaged it LED blinks rapidly before it goes dark. If you adjust the rate it will blink faster before it goes dark. Hit the switch again to go back to chorus and it works just fine. I did find a copy of the schematic. Now I am new to this and although I can slowly read a schematic, transferring that information to the PCB is beyond me. I can guess but I am not a fan of this. The best copy of the schematics I could find is still difficult to read as it is a poor copy for the small I have been unsuccessful finding a component layout for the PCB board. I do have a digital scope (not good at using it) and I can not get a signal from pin 7 of IC4. I can when using chorus and it looks to be fine. Just by guessing and process of elimination I found IC4. I really need the PCB layout. Those caps are installed correctly (polar) and are the correct uf and voltage. So any of you folks out there have any idea what could be wrong. Like I said it did work but due to the age I wanted to recap it and put in the 500k pot as I use this for guitar. Thanks for your time. Not sure it's the same version. Any chance you put an electro in backwards. Knock anything loose. In the pic there are some screws missing. In some older gear, they make grounds at the screw holes. Don't know if that's the case with the CE-1 though. The schematic I have is the same that you provided. From what I found it is the best quality out there. And luckily it is the version I need. The link to the other pictures are very useful. One of those I had and I have been using. I will be checking the others out here directly. It does show the values though and that will be nice to have. I will say that I did only change one cap at a time and I took my time at that. This is not the first vintage pedal I have worked on. I am just not an electrical engineer. Thank you and I will keep this post updated. In C35 (following the trace) I have a.47 cap and it calls for a 4.7. I did take pictures before and although I could not read that position I did have a sharpe mark on top of all the caps I was changing. The mark on top of this cap was kind of unique so I was able to dig for the old one and see that it was 4.7. Don't know how it happened. I am really cautious. Thanks for the help. It was quick and dirty just to make something where components could be found. I was not putting power to the pedal and if I recall correctly none of the screws are used for ground. I do have all the screws. Apparently I do not have a polarized 4.7uf cap around today. If I understand it correctly C35 is in the audio path. If this is correct can I use a bi-polar cap in position C35. I do have a new one of those. Otherwise I will have to put in the old cap to see if this works. The schematic does list a positive and negative side but I have heard of people replacing these with BP caps. I did not know if it would be safe to do in this case. Still learning how these circuits work. Something like this is a little complex so I am still working on the old ones. I was thinking about doing a hybrid of a tube screamer and EP-3 preamp at some point. HOWEVER I believe there still may be a problem. There is a pretty substantial audio noise it is making that coincides with the effect; it is a whooosh sound. When I stop playing I believe this has some sort of internal noise canceling because there is a audio drop as well; until you start playing again. This audio noise does not ever go away. Any ideas, from experience, to know where to start looking? Thank you. I was hoping that changing the caps would fix this. It happens on both Hight and Low input. It does not matter what mode you are in. Believe this might be the culprit for this pedal having noise in the output. The other test points look pretty good. Just a little low on the Vpp but not much. Have not adjusted anything until I see if I have a bad active component. Did you miss your activation email ? I know it's a j-fet but was looking for a part number for the original if anyone had it. It's not on any schematic I've found. I'm thinking about building a clone. So far alt. available parts have been pretty easy to find. Does anyone have more than just the schematic. Like a full service manual? This could be a good project to build. I believe retrosonic or something makes a compact ce-1 clone. Maybe also map out a mod for depth and speed pots for the chorus instead of just intensity. Besides I have an original ce-1 I can take gut shots if that'll help too. One hunch would suggest a GR suffix, while another would suggest an AY suffix.

In addition to the Rate and Depth controls, the Boss CE-300 Chorus provides a Chorus Level control to select the desired proportion of chorus effects to the direct sound. Also, by using the Chorus Tone control, any type of chorus effect desired is possible-from the popular CE-1 type mild chorus effect to one that’s extremely sharp-sounding. With unequalled ease-of-use and built to extremely high specifications, the Boss CE-300 delivers recording quality performance in the studio or Circuitry features 2 Independent chorus circuits for pitch-deviation chorus effects when the CE-300 is used In the stereo mode with 2 amplifiers. In the mono mode. a full sound like that of a multiplex chorus effect is available. For creating many different sounding chorus effects, the Boss CE-300 comes equipped with four controls. Rate and Depth controls respectively set the rate and depth of modulation. This creates the well known and well used natural chorus effect as well as producing a spacious sound. Output jack A should be used when a monaural effect is desired. Remote effects are foot switch controlled from the remote jack.Let others know what you thought of it.These things are pretty well build, sound good on guitar and keyboards.

The General Information section elaborates on how the CE-5 unfolded.Opinions of the digital (post-2001) version of CE-5 tend not to be positive.When Output B is used, Output A is pure wet signal. This forces all the wet signal through Output A and the dry signal into Output B. The wet signal is vibrato. When combined (summed) with a non-modulated dry signal, the result is heard by the human ear as a chorus sound. If using this trick be aware that without the effect level at Max, the wet signal will not have unity with the dry signal, causing a volume loss when engaged.This effect still gets rave reviews on both the lushness and subtlety of the chorus effect. The earlier CE-5 models share the same pedigree (and MN3007 bucket-brigade delay chip) as the CE-2 and CE-3 and are valued for such. Later models of the CE-5 discard the older analog design and use a new digital architecture. Panasonic stopped producing the MN3007 chip, causing Boss to change to the new digital architecture.If the pedal is white, it's newer and will be digital. If it's dark grey, it's the digital version. If they'll open the pedal up and take a shot of the PCB, even better.This is because when you find a seller of an analog CE-5, he or she will likely be unaware of any difference. It's usually possible to get a seller of an analog CE-5 to sell at a price that's the same as used digital CE-5s. Analog CE-5s can still be had rather inexpensively. Sometimes, they just take a little time and some effort to find.Our explanation is going to be a bit more complicated than that for other pedals.If phase between Output B and Output A were different, that would be a problem. We think this has something to do with the fact that the signal goes through IC2b twice. At least the way we read it, the signal goes through IC2b first, without inverting, for the low frequency filter, and then goes back through IC2b and gets inverted and then goes on its way to the high frequency filter. Of course, we're not as experienced with solid-state electronics, so this is some informed guesswork on our part; but it also helps us get to where Output A exits the pedal In-Phase.The service manual is being made available since the schematic may not be legible enough for everyone interested in viewing it.
