Do you own a Telecaster-style guitar with a humbucker in the neck and a single coil in the bridge?
One of the biggest questions with this setup is:
Do you use 500K pots or 250K pots?
If you go with 500K pots, your neck humbucker stays open, clear, and full — but your bridge single coil can become too bright or sharp.
If you go with 250K pots, your bridge single coil sounds more traditional — but your neck humbucker can become darker and less alive.
This harness solves that problem.
By using 500K CTS pots and adding a resistor to the bridge pickup side of the switch, the neck humbucker still “sees” the full 500K load, while the bridge single coil sees a load closer to a traditional 250K setup.
The result is better balance between both pickups without sacrificing the natural tone of either one.
A 470K / 480K resistor wired from the bridge pickup position to ground makes the bridge pickup see approximately 240K–250K, while the neck humbucker remains open and clear on the 500K pots.
This is an excellent upgrade for Telecaster-style guitars with:
Humbucker neck / single coil bridge
Wide Range neck / Tele bridge
P90 neck / Tele bridge
Mini-humbucker neck / Tele bridge

Testimonial from Ice – Shop Supervisor & Tone Inspector
“Hi, I’m Ice. I may not have opposable thumbs, but I do have an ear for tone and a nose for quality wood.
Every day I patrol the shop, sniffing out bad solder joints and ensuring every guitar smells like success (and maybe a little beef jerky).
Mike built me a custom dog-sized Telecaster once. I couldn’t play it... but I licked it. It passed inspection.
So if you're wondering whether to buy from Carparelli Guitars, here's my advice: Sit. Stay. Buy it. 5 paws out of 5.
Now please excuse me while I nap in a pile of tonewood.”
