Understanding the Basic Les Paul Wiring Setup
Original 50s and 60s Les Paul Wiring
The classic Les Paul wiring configuration dates back to the 1950s and 1960s, characterized by a straightforward approach that emphasizes simplicity and tonal purity. The key features include:
- Two humbucking pickups (neck and bridge)
- Separate volume and tone controls for each pickup
- A three-way pickup selector switch
- No coil-splitting or additional switching options
This setup provides a variety of tonal options, from full humbucking sounds to individual pickup selections. The wiring diagram typically shows each pickup's hot wire connected to its respective volume potentiometer, with the tone controls linked via capacitors to ground.
Components of a Basic Les Paul Wiring Diagram
Understanding the components involved helps in grasping how the circuit functions:
- Pickups: Usually humbuckers with two or four conductor wiring options.
- Volume Pots: Control the output level of each pickup.
- Tone Pots: Adjust the treble content by shunting high frequencies to ground.
- Capacitors: Determine the frequency range affected by the tone control; common values are 0.022μF or 0.047μF.
- Pickup Selector Switch: Typically a three-position switch (Rhythm, Lead, or Bridge/Neck).
- Grounding: All grounds connected to the back of the pots and bridge for safety and noise reduction.
Common Variations in Les Paul Wiring Diagrams
While the stock wiring provides excellent tonal options, many players seek modifications to expand their guitar’s capabilities. Here are some popular variants:
Coil-Splitting Wiring
Coil-splitting allows a humbucker to operate as a single-coil pickup, providing a brighter, more cutting tone. This involves adding a push-pull pot or a switch to short the series-wound coils.
- Typically requires four-conductor pickups.
- Wiring includes a switch or push-pull pot to connect the humbucker's series coils in parallel or out of phase.
- Enables a wider tonal palette, from thick humbucking sound to bright single-coil tone.
Series/Parallel Switching
This modification allows the pickups to be wired in series (standard) or parallel, significantly affecting the tone.
- Series wiring yields higher output and a thicker sound.
- Parallel wiring produces a brighter, more articulate tone.
- Usually implemented with a push-pull pot or toggle switch.
Phase Switching
Phase switching involves reversing the electrical phase of one pickup to produce out-of-phase sounds, resulting in a thinner, more hollow tone.
- Requires additional wiring and a switch or push-pull pot.
- Offers unique tonal textures for more expressive playing.
Detailed Wiring Diagrams for Les Paul Variations
Standard 50s Wiring Diagram
This diagram reflects the original design, emphasizing simplicity and vintage tone.
- Hot from pickups connects to respective volume pots.
- Volume pots connect to the switch and tone controls.
- Tone pots connect to capacitors, which are grounded.
- All grounds linked to the back of the pots and bridge.
Modern 50s Wiring with Coil-Splitting
Features a push-pull pot on the tone control to activate coil-splitting.
- The push-pull switch toggles the humbucker between full-series mode and single-coil mode.
- Wiring includes extra connections to the pickup's four-conductor cable for coil-splitting.
Vintage Wiring with Series/Parallel Switch
- Adds a dedicated switch to toggle between series and parallel wiring.
- This switch modifies the wiring between pickups and pots.
Custom Wiring for Multiple Options
Some players prefer complex wiring setups with:
- Multiple switches for coil-splitting, phase reversal, and series/parallel options.
- Additional tone controls for different frequency ranges.
- Diagrams for such setups often include multiple push-pull pots and toggle switches.

Frequently Asked Questions
What are the essential components of a Les Paul wiring diagram?
A typical Les Paul wiring diagram includes pickups (usually humbuckers), volume and tone pots, a selector switch, and output jack. The diagram shows how these components are interconnected to control the guitar's sound and switching options.
How can I modify my Les Paul wiring for coil splitting?
To add coil splitting, you need to modify the wiring by adding a push-pull pot or a switch that disconnects one coil of the humbucker. The wiring diagram will show the specific connections to enable single-coil operation while preserving the humbucking mode.
Where can I find reliable Les Paul wiring diagrams for different pickups?
Reliable sources include official Gibson wiring diagrams, reputable guitar forums like The Gear Page, and specialized websites such as Seymour Duncan or StewMac. These resources offer detailed diagrams for various pickup configurations and modifications.
What is the difference between a standard and a treble bleed Les Paul wiring setup?
A standard wiring lacks a treble bleed circuit, causing treble loss when turning down the volume. A treble bleed wiring adds a capacitor and resistor to maintain the high frequencies when adjusting volume. The diagram illustrates how to incorporate this circuit for clearer tone at lower volumes.
Can I customize my Les Paul wiring diagram for active pickups?
Yes, customizing for active pickups involves adjusting the wiring to accommodate the preamp or battery-powered circuitry. The diagram will include additional connections for power supply and may differ from passive wiring diagrams, so refer to specific active pickup wiring guides.
How do I troubleshoot a Les Paul wiring diagram if my guitar isn't making sound?
Troubleshooting involves checking each connection in the wiring diagram for continuity, inspecting solder joints for cold solder or breaks, and ensuring components like pots and switches are functioning properly. Using a multimeter and referencing the wiring diagram helps identify and fix issues.
