BOSS CE-2 Vintage Chorus Pedal

Not sure what year. Looks like the standard flat head screw has been replaced. (photo) No label. Info painted in yellow by input jack and power cord input. (photos) In very good shape. Works great, nice and quiet. Bought this a while back, don't really use it. If you're after that classic '80s chorus sound, this is the ticket. LOCAL PICKUP IN CHICAGO ONLY. OPEN TO POSSIBLE TRADES FOR OTHER QUALITY PEDALS, NO CHEAP CRAP SUCH AS JOYO OR MOOER PLEASE.
