this one has me p[uzzled. I got an original API 550A that was pulled from an API console( Vintage custom) because when the eq is plugged in, the corresponding channel has audible distortion. Without the eq the channel sounds good and if I patch around the eq audio is good. Yet I can't duplicate the distortion other then having the eq in the console. If I take the eq and use it in an API 500 series rack, it works flawlessly and sounds good. More over if I move the eq around to a different channel, the distortion follows the eq.
Is there a difference in pinouts between vintage console and 500 series rack?
