Hi, can anyone help me set my (Russian)Bass balls back to the default position. If you take the pedal apart and look on the circuit board there are two small holes beneath which are two small adjustable pots. What I'd like to know is at what time (o'clock) are the two pots set to? If you turn these pots you can set the frequency points of the two dynamic filters. This can produce some interesting sounds but the problem I have now is I can't find the default sound.
