I have problem with Shadow 965 NFX pickup. I just installed pickup on my bass. It gives decent quality signal. But when I move cable (bend it away from bass) it starts to buzz. Even when I am playing and making louder note it starts to buzz. I tried 3 different cables - the same result. When I wrap cable around tailpiece, so cable is not moving, it helps. I will send it back for warranty check, but I have gig tomorrow and I want to use this pickup. My other bass is not in "gig condition". Any suggestions how to deal with this problem?
