Yo, I just bought a used 303 on ebay and am getting no response from the right two knobs of the SP (Resonance/Drive knobs). Like when I put an effect on I can see the values for the knobs flashing but when I try to change the values they seem to have a mind of their own. Opened up the unit and all solder joints seem intact. Any idea what's wrong or suggestions for a quick fix?
Thanks,
D
