The CE-2 took theThe early CE-2 used the 3007 bbd chip, later Japanese CE-2 pedals used the 3207. The 3007 chip was used in theAny hint is highly appreciated. Other than that we'rePlease submit your offers or leads here: e-mail. 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.http://angelescare.com/userfiles/bose-pm-2-manual.xml 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.https://formations.fondationmironroyer.com/en/node/8890 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.

Three years later, this inventive new sound was squeezed into the blue CE-2 Chorus, and chorus pedals have remained in the compact lineup ever since. Four decades on, the spacious modulated tone of the signature BOSS effect is still loved by musicians everywhere. In 2016, to celebrate the 40th anniversary of BOSS innovation, the original analog chorus sounds are now reborn with the Waza Craft CE-2W. The CE-2W’s Standard mode faithfully recreates the classic CE-2 chorus sound, and adds an expansive new sound field with stereo output, which was unavailable in the mono CE-2. CE-1 mode fully reproduces the stereo chorus and vibrato sounds of the legendary CE-1, with the addition of variable chorus depth not available in the original pedal. To commemorate the birth of BOSS effects, the CE-2W is made exclusively in Japan, just as the original CE-1 and CE-2 were. Released the following year by Roland’s newly formed BOSS division, the stereo CE-1 Chorus Ensemble made it possible for players to achieve the lush, spacious chorus and unique vibrato sounds of the Jazz Chorus with any amplifier setup. While both of these effects sounded great in mono, the CE-1 offered up its real magic when used in stereo with two separate amps. This delivered an incredibly rich and immersive sound experience that was a true joy to play. The CE-2W provides an authentic reproduction of the CE-1’s analog sounds, with additional chorus adjustment now possible with a variable depth control.https://dsodrecital.com/wp-content/plugins/formcraft/file-upload/server/content/files/1626d8c3828c58---3m-x20-multimedia-projector-manual.pdf In 1979, these demands were answered with the CE-2 Chorus. This refined chorus tone was an instant success, becoming the go-to sound for hit guitar tracks throughout the 1980s and beyond. In addition to authentically producing the CE-2’s original mono-only sound, the CE-2W makes the classic pedal’s soft modulated tone available in true stereo for the first time ever. Bringing together the cutting-edge technology of the time, savvy craftsmanship, and a devotion to helping musicians create great music, these landmark pedals embodied the spiritual mission for every BOSS product since. For this memorable 40th anniversary, the Waza Craft CE-2W Chorus is produced in Japan just like the original pedals, honoring the long, rich heritage of BOSS effects. This enthusiastic spirit continues on with the Waza Craft series, which brings you exceptional tone and touch response through carefully selected analog components, refined circuitry, and meticulous attention to detail. In Japan, “Waza” is the term for art and technique, and these special edition pedals proudly carry the Waza symbol to represent the pinnacle of BOSS design and craftsmanship.

The CE-5 began as a continuation of the same chorus circuit as the Boss CE-2 and CE-3. 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.http://plenar.hr/wp-content/plugins/formcraft/file-upload/server/content/files/1626d8c45049fc---3m-x20-projector-user-manual.pdf 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.

The CE-3 had the MN3207 chip and most people think they don't sound as good.

Unfortunately I didn't see MIT version PCB to tell something for sure. If you can kindly make a close shot of your MIT PCB and post it here or PM me I can try to tell more about the differences in the design. I found the only MIJ vs MIT Youtube comparison quality enough to make some sonic judgment. Funny that the guy forgot to name the pedals in the beginning of the video so you can try to guess. My guess was right. I think MIJ is capable of higher quality chorus sound. But it's not clear if it's Black label or Green label MIJ pedal. Regardless these two pedals definitely sound different. Thanks for the good shots of your MIT and MIJ. Here's mine: Cool pedal!

Some part variations possible even within the categories while the design progressed along the years. Where sound differences between the pedals may come from? - Cap and resistor values may vary a bit through the years. I can't see the values from the pics. Note Service Manual for CE-2 didn't change. Yours is JRC4558DD, mine - NEC C4558C (Japan). Note some MIJ Black Label versions also use JRC4558D. So it's not consistent. - Q1-Q3 transistors. Mine are 2SC732TM-GR (NPN silicon transistors, same as the schem reads). Don't know which trannies are used in MIT. But I doubt it may noticeably affect the sound anyway. - MIT uses different type of film caps. There's a lot of filtering in the schem. It may contribute to the sound variations. - VR3 trim pot. It has optimal position and shall be tuned at the factory. But there were so many advices to change the default setting. So you never know if the setting of yours was altered. - Parts that are labeled the same but manufactured decade later at a different plant may vary. So what? I'd say all the above mean the sound may vary even withing the mentioned CE-2 categories. If you want to get well sounding CE-2 you may need to try a few different CE-2 pedals regardless of the label and find the one that sounds best. But there's also a shortcut. Just get yourself any CE-2 and be happy! Sorry too busy to pul them out again. Sorry too busy to pul them out again.They were a big secret at the time I got mine, as they are so close to the regular CE-2, but a lot cheaper to buy. I think by now the secret is out, and they have gone up in price. I think the mod is just a change to one component that changed the range of the effect to work better with bass, but I decided to leave mine stock, as it sounds great that way for guitar. Al Sorry too busy to pul them out again.Obviously CE-2B diagram is slightly different. But essentially it's the same circuit. All these diagrams and multiple PCB pictures I managed to find make me believe MN3207 based CE-2 is just a myth effectively created by Boss Area 2.0. I suppose they are both poly metal film. I invoke you ! I’ve now used an Emperor as my chorus pedal of choice for about a year - superb pedal imo. This pedal gave musicians a greater range of control, from subtle vibrato sounds to thick, syrupy chorus. In fact, the basic design and tone of this pedal lives on to this day in its descendent, the CE-5. Boss CE-2 chorus shootout by deniki4 Boss CE-2 by deniki4.
