Gibson SG Wiring Diagram: The Ultimate Guide for Guitar Enthusiasts

If you are a guitar enthusiast, you are probably fascinated with the Gibson SG guitar, one of the most iconic and recognizable guitars in the world. This guitar has been used by some of the world’s most celebrated guitarists, from Tony Iommi of Black Sabbath to Angus Young of AC/DC. One of the most important things to know about this guitar is the wiring diagram, which is essential for any guitarist to get the most out of their instrument.

What Is a Wiring Diagram?

A wiring diagram is a visual representation of the electrical connections and wiring of a guitar. It shows how the various components, such as pickups, switches, and pots, are connected to each other and to the output jack. A wiring diagram is essential for troubleshooting and modifying a guitar’s electrical system. While it may seem intimidating at first, understanding the wiring diagram is essential for any guitarist who wants to get the most out of their Gibson SG.

The Basic Gibson SG Wiring Diagram

The Gibson SG features a relatively simple wiring diagram, which consists of two humbuckers, a three-way switch, and two volume and two tone controls. The diagram is as follows:

Wire Color Function Terminal
Black Ground N/A
White Bridge Pickup Hot 1
Green Neck Pickup Hot 3
Red Common (Switch Terminal) C
Yellow Output 2

As you can see from the diagram, the pickups are connected to the switch, which allows the guitarist to select between the neck and bridge pickups, or both at the same time. The volume and tone controls allow the guitarist to adjust the sound of the guitar, while the output jack sends the signal to the amplifier.

Wiring Modifications for the Gibson SG

While the basic wiring diagram for the Gibson SG is relatively simple, there are several modifications that guitarists can make to customize their instrument to their liking. Some of the most common modifications include:

Coil Splitting

Coil splitting is a popular modification for humbucker pickups, which allows the guitarist to switch between a single-coil and a humbucker sound. To achieve this, the two coils of the humbucker are split, and only one coil is used at a time. This is achieved by adding a switch or push-pull pot to the guitar’s wiring diagram.

Series/Parallel Switching

Another modification that can be made to the Gibson SG’s wiring diagram is series/parallel switching. This allows the guitarist to switch between a series and parallel wiring configuration for the pickups. In series mode, the pickups are wired in a series, which gives a thicker and more powerful sound, while in parallel mode, the pickups are wired in parallel, which gives a brighter and more transparent sound.

Phase Reversal

Phase reversal is another modification that can be made to the wiring diagram, which allows the guitarist to switch the phase of one of the pickups. This can create interesting and unique sounds, and is often used by guitarists to achieve a more complex tone.
