In this post, we’re going to show you how to install the Seymour Duncan ST59-1 humbucker pickup into your guitar.
Seymour Duncan st59-1 wiring — let’s start with some basics: The ST59-1 is a mini-humbucker, designed as a direct replacement for the bridge pickup in a Fender Telecaster, but it will also work well in many other situations. The ST59-1 offers players hum-free operation and a thicker tone that still retains plenty of Tele Twang. This pickup is installed into your guitar using four colored conductor wires and a bare wire.
A common source of confusion when installing any humbucker pickup is the multiple colored wires. If you look at the “features” part of many humbucker pickup description, you will often see one of the features labeled “4-conductor wire.” The four colored wires are called “conductor” wires. They are called this because each of these wires carries current to and from the two coils in the humbucker. Each coil has one positive and one negative wire. Which color is positive and which color is negative is called the pickup’s “Wiring Code.”
Unfortunately, there is no standard Wiring Code, and it varies between manufacturers. The Bare wire is the Shield, and it is not connected to the coils. Its primary purpose is to trap radio frequencies that reach the pickup and shuttle them to ground before they degrade your signal. The Shield is always soldered to Ground.
For the Seymour Duncan ST59-1, one coil uses Green and Red wires, and the other uses Black and White wires. (Fig 1)
The “Standard” way to wire humbuckers is in Series. Series means that we run one coil right into the other to create one long continuous path for our signal to travel. This makes the humbucker almost twice as loud as a single coil, and it is also responsible for its warmer tones. There are many different ways that we could wire it though, and that is the reason why we have so many wires. For now, we will do it the Standard way.

Installing the Seymour Duncan st59-1 Wiring
To install the ST59, we begin by considering the Black wire to be the Hot wire. We solder together the Red and White wires and tape them off, and we use the Green wire as the Ground wire. It’s standard practice to solder the Green and Bare wires together. (Fig 2)
Now we are left with the positive (Black) and negative (Green) wires that we will need to install our pickup.
Connecting to a Volume Control
First, solder the Green Negative wire and the Bare wire to the back of the Volume pot, which is the standard place to solder all Ground wires. (Fig 3)
Next, we will solder the Black wire to the first tab on the Volume control. Most people solder the third tab to the back of the Volume pot, either with a short wire or by physically bending the tab until it contacts the back case of the potentiometer and soldering it in place. (Fig 4)
Next, we connect the Volume Control to the Output Jack by running one wire from the center tab of the Volume pot to the Output Jack, and one from the Output Jack to the back of the Volume Control. (Fig 5)
Adding a Tone Control or a Switch will only add more components and will not really change this circuit that much. Look around humbuckersoup.com for other ways that you can wire your humbucker and open up your tonal possibilities.
