Passive Harness



We are pleased to be able to offer our own custom pre-wired passive harnesses. Each of our custom pre-wires are built in house and utilize only the highest quality electronic components.Whether it be a P Bass with single Volume & Tone, or a Jazz Bass with either a Volume, Volume, Tone or a Volume, Blend, Tone or something more complex these harnesses make a perfect addition to any passive build. Each prewire is custom built specifically for your bass. We use quality potentiometers, Sprague Orange Drop Capacitors, and Switchcraft Stereo Jacks. Only soldering that is required is to wire in your pickups, & bridge ground wire. Average completion time is only a few days on average.

Shipping Note on Prewired Units:

Prewired units are created based on your individual order.

This means that our technicians are custom wiring your order within days of completing your order with Best Bass Gear.

If you choose expedited shipping options that does not expedite the time taken to custom wire your particular item.
