Premium Wiring Kit for Jazz Bass

About This Item

All of the wire and components you need to wire a 2-pickup guitar or bass.

Jazz Basses® don't use a selector switch to control what pickup is active, they use two volume controls that allow you to blend the pickups together. Here's what you need for wiring those pickups into your J-bass! All the parts, plus a diagram to show you how.

The premium kit features cloth-covered push-back wire—the right wire for Fender and vintage-style guitar circuitry. The pots in this kit are upgraded to CTS brand for longer life and a smoother, more accurate response.

This setup can be used for basses and guitars, or you can add a selector switch (sold separately) for added flexibility.

    Wiring kit for Jazz Bass includes
  • Output jack
  • 250K CTS control pots (3)
  • .047uF Orange Drop capacitor
  • Non-shielded cloth-insulated push-back circuit wire: 22 AWG, white, 12" long
  • Non-shielded cloth-insulated push-back circuit wire: 22AWG, black, 24" long

Easy to use this kit

(Customer's Reviews)

Everything you need to quickly prepare the Jazz bass control plate makes it worth the price.


Great basic kit for a bass!

(Customer's Reviews)

It's a great start to upgrading a bass. Stew-Mac needs to allow upgrades on checkout, better caps (I used a Hoveland film capacitor that I have hoarded) like oil filled or film caps. They also should allow for the selection of different output jacks. The one in the bass kit wouldn't work as it was for a thin instal. I had a Washburn base with a reaf pocket like a Les Paul, so I needed long or barrel jack. I used the original jack after testing it for continuity and retention.

Good product,...provided a bit of a challenge!

(Customer's Reviews)

This kit was definitely not made to fit the Japanese made Fender Aerodyne Jazz bass. Some workshop engineering and creative thinking was required to install and wire up this kit. Had to be careful with some of the fraying shielding not making contact with any of the pot's solder lugs. All said and done, the result was a fantastic sounding J-Bass
