I hear guys producing awesome tones with the OC-2. I have never been able to get a useable tone from mine. I have an old Tiawan built unit for many years. No matter the signal I send it I get clipping all over the fingerboard with active and passive basses. The tone I am trying to achieve is the OCT 1 maxed out no clean. If I put fuzz in front its gets worse. If I put it behind its even less usable. Is my pedal defective? I am feeding it 9V from my Noble Pre. I would expect that to be nice clean power, but maybe not? Any input would be welcome, I want this tone, I must be doing something wrong.
