Boss CE-3 Chorus from 1983. Black label. Made in Japan. Play-tested as of April 2024 with PSA cable as well as 9V battery; both work as intended. Knobs work great, adjusting levels from slow wave to rapid wobble. Marked as "good" due to various paint scratches, wear, and faded back label, but it's fully functional and works great. OEM circuit board shield and thumb screw grommet have been replaced with comparable material. No box or paperwork; pedal will ship with packing material for protection. Ask any questions before buying.
