Now with Two Options 

Traditional Vintage Plus 


This is our original and most popular wiring harness for Jazz bass. Just like the originals but will all of our Obsidian® tweaks for smoother volume and tone controls and crystal clear clarity.

To make your tone crystal clear at lower volumes we also include an Obsidian® Custom Spec Treble Bleed Mod. This prevents tone 'muddiness' at low volumes by allowing high frequencies to pass along a separate path to your amp, rather than being stopped short by the increasing resistance at the volume control.

True Vintage 63'


This is the Obsidian® re-production of the true vintage Jazz bass wiring used from 1963, the first year of the three control layout, that is still used on most Fender Jazz Basses to this day. 
This set is designed to replicate the original sound of a 60s Jazz Bass, with 250k tone and volume controls, and a 0.5mfd capacitor. 
Unlike our Traditional Vintage Plus and custom sets, there are no modern adjustments. Just bold thundering bass. Just like the originals.
