It has the LM308N chip and the pot codes are 1378635. 35th week of 1986.
These "blackface" were only made for one year (the earlier "whiteface" small box was made 1984-1985, then came this "blackface" model in 1986). They changed in 1987 and those versions were not as good.
Everything works as it should. I guarantee it will not disappoint you. The battery cover is missing, so it is priced accordingly.
Save some on a great sounding vintage rat!
ProCo provides a free battery cover if you let them know you need one for the pedal.
Thanks for viewing!
