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.

I was so tired of 2 volume controls on my jazz basses. This unit solved all my problems. Will be ordering more and replacing all my passive jazz bass control plates with these..

I just wanted to compliment your company on a quality product. Your website proved to be much help first and foremost when searching for the perfect control layout. I then discovered your pre-wired harnesses for a person who was not blessed with the soldering hand. I love that the leads are already attached so I didn't have to ruin your company's beautiful joints when connecting my ground and pickups. Overall, I just wanted to say thank you on a site, harness, and job well done!
