    I just purchased online a pedal vintage “Octave Multiplexer”, however does not work. To open it (I have knowledge in electronics), I am aware that need integrated circuit which is near the potentiometers (7-pin side). Anyone know what CI is in this position? The Board indicates year of construction: 1975.
