ObsidianWire Introduces J and P Bass Wiring Upgrades
Attention mod junkies: ObsidianWire has just unveiled a J and P-bass upgrade wiring harnesses. Utilizing solder-less connectors, the sets are designed to be drop-in replacements for American and Mexican series Fender basses.
Both harnesses are built with hand selected and matched CTS pots that ObsidianWire says offers greater clarity and consistent response. Other features include NOS paper in oil capacitors and a treble bleed/volume mod that retains treble when you roll back your volume.

While the harnesses are designed for Fender J and P-basses, ObsidianWire states that the connectors work with any standard two-wire pickup and many pickups with an extra ground wire such as Lace sensors.
The kits are available now with prices of $62.99 for the P-bass harness and $69 for the J-Bass harness.
