Introduction

In this guide you will learn how to replace the output jack. Output jack replacement will need to be done if your bass no longer makes sound, the bass only makes sound when the cable is orientated awkwardly or the bass cuts in and out when the cable is moved. Your output jack can break because the delicate metal parts which make contact with the instrument cable have been worn out or bent out of shape. Sadly, this Ibanez series bass uses a closed output jack, thus it is impossible to fix, and can only be replaced.

Locate the gold nut at the base of the output Jack.
Do not remove the nut completely, but leave it about halfway down the output jack. We only want to move the prongs slightly away from all of the wires to allow for easier soldering.
Use the wrench to loosen the nut.
