Choosing Your Capacitor Value
Traditionally, J-Basses use .047µF. However, our kits give you the option of three different capacitor values so you can choose how much top end you want rolled off with the tone pot(s):

• .015μF rolls off the least amount of top end
• .022μF is the median value
• .047µF rolls off the most top end when your tone pot is turned down.

To help you choose the capacitor that best fits your needs, be sure to watch our videos on Capacitor Values and Capacitor Materials.

More About Our Pre-Wired Kits
Our kits are hand-wired by Lollar Pickups in the USA to Jason Lollar's preferred specifications. They feature Lollar spec'd CTS potentiometers with a special taper for an even range of volume and tone adjustment, high-quality Switchcraft 1/4" output jacks, and your choice of Orange Drop Poly Film-in-Foil or Bumblebee Paper-in-Oil capacitors.

We've also put together a video on Soldering Basics that may be helpful to watch before installing your pre-wired kit.

*THESE KITS ARE BUILT WITH THE CONTROLS SPACED TO FIT STANDARD USA FENDER JAZZ BASSES. CONTROLS ON IMPORT GUITARS MAY BE SPACED DIFFERENTLY.
If you are installing the kit on an import guitar with metric-sized pots, you may need to ream the holes for your controls (AVOID USING A DRILL BIT) to accept the slightly larger US-spec pots (3/8" shaft diameter, 24 spline) and purchase US-spec knobs.

PLEASE NOTE: All prewired kits are built-to-order as custom work, may take three to five business days before shipping, and are not eligible for return or exchange. Prewired kits are thoroughly tested after assembly, if you have a problem with any of the wiring components during installation, STOP, do not remove or replace any of the components from the prewired kit and contact our customer service team at info@lollarguitars.com or (206) 463-9838 for warranty service. Prewired kits that have been altered or had components replaced are not eligible for warranty service.

Ok... so there aren't any reviews yet, but there will be soon, we promise!

Frequently Asked Questions

Do you offer loaded pickguards or sell your pickups wired to a complete wiring harness?
We are not able to offer loaded pickguards, nor are we able to wire our pickups to a prewired kit.

Can you do custom options for prewired kits like push/pull pots, additional toggle switches, et cetera?
We are not able to do custom configurations. However, you can order the pots, caps, switch, and jack as individual components and configure them however you like.

Will your pots fit my import guitar?
Many import guitars use metric units of measurement for their component sizes. Import guitars often have pots that have smaller diameter shafts than US made guitars. If you are replacing the electronics in your import guitar with our prewired kit, you will likely need to enlarge the holes for the volume and tone pots. A hand reamer tool is perfect for this job.
