Boss CE-2 Chorus pedal made in Japan 1980, in working condition with wear from use and age, including: marks/scratches, residue and a hole on the bottom of casing from prior owner pedalboard mounting, and missing label. Runs on 9v battery or power supply (not included). The depth knob works and alters sound, but the knob does not seem to have complete range of motion and the potentiometer may need replaced.
