I bought a used jazz bass and the previous owner had another output jack installed in the side of the body in order to accomodate for an active preamp which he later removed. I want to keep the bass passive with the regular old volume, volume, tone, jack setup on the top of the bass in the control cavity. Is there a way to fill in the space on the side of the body where the jack is/was? I don't have any pictures of the bass unfortunately, but the attached picture shows what the jack looks like, so there are four screw holes and one 1/4" hole for the instrument cable in the body. Thanks so much for your time!
