Hi, I have this question regarding my Fender Jazz Bass '62 RI CIJ. - With std. factory pickups. My sound is quite different on each string. The biggest difference is on the A string. It sounds like the pickup is clipping, when ever I play just a teenie-weenie little bit aggresive. I don't think it's the neck - it seems OK. (No probs. with the other strings) Would it be likely, that it's the Pickup that needs to be replaced? I'm looking forward to your reply.
