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
  • Shielded braided push-back circuit wire: 22 AWG, 12" long
  • Wiring diagram

Easy to Wire!

(Customer's Reviews)

Purchased this kit to replace the miniature pots and inferior output jack on a Jay Turser Jazz Bass. Needed to drill out the plate to 3/8" to accommodate the CTS pots as noted on the website. The wiring instructions were clear and lots of wire was provided! Easy upgrade!


Great Kit!

(Customer's Reviews)

Order arrived earlier than expected and they have great customer service! This kit is perfect for wiring up your jazz bass! I bought a push pull pot and replaced one of the standard pots with that for the series/parallel mod, but this kit gets you everything you need!!


Squier Bass

(Customer's Reviews)

The original wires and pods were junk in my bass. Highly recommend these to anyone having a cheaper bass.


Always best quality 

(Customer's Reviews)

Looked for less expensive parts, but the quality was not there.


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


Nice one

(Customer's Reviews)

Very hand piece of kit, plenty of wire, pots nice and solid with plenty of range. HAd to redrill control plate as mine had the nasty alpha size pots. Only thing I would wish for, that CTS would put a solder lug on the case of the pots, asways a bit wary of putting too much heat on them. Good buy.


Great improvement for the money

(Customer's Reviews)

I installed the premium kit on a new Squier VM Jazz Bass. The only thing I had to modify is the control plate; the holes for the controls were just barely too small for the knobs to fit through, so I had to dremel them to make the holes larger . . . after re-wiring it sounds SO MUCH BETTER! I recommend this to anyone that has a Squier J Bass.


Measure your existing pots first!

(Customer's Reviews)

I purchased this to upgrade the wiring in a Squier bass and it actually improved the sound a bit over the cheap factory wiring. The only downside is that these are full size pots so they were bigger than the tiny factory pots so I had to rout a larger control cavity. If you're sure this will fit in your bass, you're golden. If you have small pots, you may have to enlarge the cavity, something preferably left for a pro. Either way, worth the money!
