The CE-1 was released 1976 and contained the exact same circuit as the Roland Jazz Chorus JC-120 Amp.The CE-2 builds on the legacy of the CE-1 but isnt identical.The middle region is boosted in the CE-2 compared to the CE-1.According to the design engineers this may be because the CE-1 had a lower input impedance.Roland says that they stopped marketing the CE-2 November 1982.
Thanks to its extremely durable made-in-Japan construction, many original specimens are still around and sound great. If you want a classic no-frills chorus, this is the pedal to get.

But applying the same filtering to the delay signal, the output signal will reduce any hiss acquired via the delay path. It adds a dreamy modulated sound that creates a dramatic ambient guitar tone. 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. 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 usual delay times are around 5 to 50ms and LFO oscillating frequencies are up to 20Hz. 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 top of the board contains all the pads to attach the cables to be connected to the jack connectors, potentiometers, and the footswitch. As a rule of thumb, the input impedance should be at least 1 M. 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. This configuration can activatedeactivate the effect using a simple push button. The JFET Bypass Switch enables two possible toggle configurations. For a detailed information check the Tube Screamer Switching Circuit. The resistors junction (4.5V) is decoupled to ground with a large value electrolytic capacitor C 18 47uF. 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. Boss Chorus Ce-2 S Series Resistor R53The 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 is implemented with a plain Emitter Follower with unity voltage gain (G V 1). It also separates the guitar from any pedal DC potential, protecting the pickups in case of circuit failure.
