Overview
The BOSS CE-2 Chorus isn't a flashy pedal, but it hums with quiet authority. Released in 1979, it entered a market already enchanted by the lush stereo chorus of the Roland JC-120 Jazz Chorus amplifier—a sound so defining that Boss sought to shrink it into a box. The CE-2 was their answer: a compact analog chorus unit designed to replicate that amp’s dreamy, swimming modulation. Owners report it delivers exactly that—warm, rich, and dimensional, with a smoothness that later digital or solid-state attempts often struggle to match. It quickly became a staple on pedalboards, prized not for complexity, but for its ability to thicken a guitar signal without muddying it. The effect sits in the mix like a second instrument playing just behind the beat, subtle but undeniable. Over time, it earned a reputation as iconic, a status cemented by decades of use in studios and on stages. Though simple in layout, its circuitry reflects a meticulous analog design philosophy, and its build quality—especially in the early Japanese-made units—has proven nearly indestructible.

Key Features
Rate, Depth, and 2-way Mode Switch
With only three controls, the CE-2 strips chorus down to its essentials. The Rate knob adjusts the speed of the modulation, from slow, seasick undulations to faster, shimmering flutters. Depth governs the intensity—how far the pitch wavers—allowing players to dial in anything from a barely perceptible thickening to a full-on warble. The 2-way Mode Switch toggles between two distinct chorus voicings, though documentation doesn’t specify their exact tonal differences.
9V Battery and AC Adaptor Power
Originally, the CE-2 ran on a single 9V battery or a Boss ACA-series AC adapter. Many modern power supplies deliver regulated 9V DC (PSA standard), which the stock CE-2 cannot accept without modification. As a result, unmodified ACA-compatible models are increasingly rare, and the lack of a standard DC jack became a well-known pain point.
Converted to PSA 9vDC
To survive in the modern pedalboard ecosystem, most CE-2s in circulation have been modified to accept standard 9V DC power. This conversion—common enough to be noted in listings— Units advertised as "converted to PSA 9vDC" are often more desirable to players who want plug-and-play reliability. Either way, the prevalence of this mod speaks to the CE-2’s enduring utility and the lengths users will go to keep it functional.
Extremely Durable Made-in-Japan Construction
This construction gives it serious heft—owners report it feels nearly indestructible, able to withstand years of stomping and travel. The "MIJ Japan" stamp on early units isn't just a label; it signifies a period when Boss’s Japanese factories set the benchmark for pedal durability. Screws, jacks, and switches were built to last, and many units from the early 1980s still function perfectly today. This robustness contributes significantly to its collectibility—finding a working CE-2 isn’t rare, but finding one with original paint and no dents is.JFET Bypass Switch
Unlike later Boss pedals that adopted mechanical footswitches for true bypass, the CE-2 uses a JFET (junction field-effect transistor) to switch the signal. This means the pedal never fully disconnects the effect circuit from the signal path when off. The JFET system was standard for Boss at the time and contributes to the pedal’s reliability—fewer moving parts mean fewer points of failure. Still, the lack of true bypass is a noted limitation by today’s standards, especially when stacked with other buffered pedals.
Historical Context
The CE-2 arrived in 1979, a time when analog effects were reaching peak refinement. Its development was closely tied to the success of the Roland JC-120 Jazz Chorus amplifier, whose stereo chorus became a sonic benchmark. Boss aimed to capture that amp’s character in a portable format, and the CE-2 was the result. It filled a growing demand for high-quality, reliable stompboxes that could deliver studio-grade effects on stage. While production end dates vary by source—some claim 1988, others 1990, and Reverb lists 1992—what’s clear is that Once the CE-3 launched, Boss typically phased out the older model, though production may have continued for a time to fulfill existing orders.
Collectibility & Value
The CE-2 holds steady in the vintage pedal market, with prices reflecting its reputation and scarcity of unmodified units. Modified examples sell for around $279.99 in good condition, while original Japanese-made models are estimated to fetch $200–$250. A 1988 Taiwan-made green label unit recently listed for $259.00, suggesting label and origin influence pricing. This has made original, unmodified units with intact power systems increasingly rare and sought after.
