Hello everyone, looking for some insight about my new (to me) 1990 Boss CE-2. Snagged this for a decent price and it sounds magical, my chorus search is over. The pedal has a sweet blue LED that was a nice surprise so I took off the base plate for a poke about. Check out the green side of the circuit board that has an added resistor, anyone know why this is here? Something to do with the ACA power being converted to PSA? Any help or opinions would be appreciated.
