G.A Pro Les Paul Solderless PCB Wiring Harness – 500K Long Shaft Pots
Part of our Guitar Anatomy Pro Range, this premium solderless PCB wiring harness offers a modern, convenient solution for upgrading or replacing the electronics in your Les Paul-style electric guitar.
Featuring an integrated printed circuit board (PCB) with four 500K long-shaft potentiometers, this harness delivers the familiar control layout of a traditional Les Paul while eliminating the need for complicated point-to-point wiring.
The solderless plug-and-play design makes installation straightforward, allowing you to connect compatible pickups and associated wiring without reaching for a soldering iron. Whether you’re assembling a custom guitar, replacing ageing electronics or upgrading your existing wiring, this harness helps make the process quicker, cleaner and more accessible.
Traditional Les Paul Controls, Modern Construction
The harness features the classic 2 Volume, 2 Tone (2V2T) configuration, giving you independent volume and tone adjustment for each pickup.
The four 500K potentiometers are particularly well suited to humbucker-equipped guitars, helping preserve clarity, brightness and definition compared with lower-value pots.
Integrated 223J (0.022µF) tone capacitors provide smooth, progressive treble roll-off, allowing you to move from bright, articulate sounds to warmer, rounded tones using your guitar’s existing controls.
Solderless Plug-and-Play Installation
Unlike traditional wiring harnesses, which require multiple soldered connections between potentiometers and capacitors, this G.A Pro harness uses an integrated PCB with solderless connections.
This offers several practical advantages:
- No soldering required when using compatible solderless connections
- Simplifies electronics installation and replacement
- Reduces complicated wiring inside the control cavity
- Provides a tidy, organised circuit layout
- Makes future electronics maintenance and upgrades more convenient
The integrated design is particularly useful for guitar builders looking for a straightforward electronics solution without the time and complexity of assembling a traditional wiring harness from individual components.
500K Long-Shaft Potentiometers
The harness comes fitted with four 500K potentiometers featuring long threaded brass shafts.
These are particularly suitable for Les Paul-style guitars with thicker or carved-top bodies, where standard short-shaft potentiometers may not provide sufficient mounting clearance.
The 500K resistance is a popular choice for humbucker pickups, helping maintain high-frequency detail while providing familiar, responsive volume and tone controls.
