Control Configuration

  3. Tone


This 3 control passive prewire is intended for instruments with 2-pickups, and a single tone control like the Fender Jazz ® bass.

These prewires are built in house by hand and utilize high quality Noble 250k Audio Taper Potentiometers, Sprague Orange Drop 0.047µF capacitors, and Standard Switchcraft Jack.

The Noble pot shafts are 6mm splined, split-knurled shaft. These can be converted to 1/4" if necessary using brass pot sleeves.

Please Note:

The prewire is built with wire lengths for a Jazz ® Bass utilizing the standard control plate. If a different length is required, please specify on your order comments.

a breeze
By Ray Klass from on 11/15/2016
I wanted to go back to passive so I pulled out a set of active EMG's from my 1983 Fender USA Jazz Bass and replaced it with a set of Bartolini's and this prefab harness.
The dime size pots blend together nicely and fit into the cavity with room to spare and to make a long story short I am very happy with the mod.

Great Set

This set worked great in my custom bass with Jazz pups. Sound is great but be warned that the wire they give you is really short. I had a hard time connecting to them. But that's an easy fix.

Noble (Dime Size) Potentiometers with Sprague Orange Drop .047 tone capacitor. All cabling are professionally soldered. Have 'em in all my Fender Jazz Bass. Much better than stock electronics.
