This is a BOSS CE-2 from the Made in Japan era. It generally has a refreshing sound with less harshness, but it still makes its presence known even when the effect is applied deeply. It worked well not only with guitars but also with bass guitars. Operation has been confirmed with a 9V adapter. Although it is marked as ACA specification, the LED lights up properly even with a standard adapter. It is possible that a common modification has been made. The word "Chorus" appears to have been erased once and rewritten with a marker. There are traces of sticker removal on the top of the enclosure. Considering the condition, the price is set lower than the market average. If you are looking for a vintage pedal that you can use without worry on the job, please consider this one.
