Thanks for the reply. It still makes an audible noise thru the amp when plugged directly into the amp without the pedal. I guess I'll exchange it this week for a new one. I love the tone, feel, and style of the bass, so I want the best possible example I can get!I Think you're right, however I'd sure try the whole process with out the pedal, just a cord straight into your amp as way to confirm. I've had various T Bird pups squeal and feed back too, none ever actually needed replacing as it turned out.
