*ΔGW Vintage Spec* Les Paul Wiring Harness

Vintage Spec Les Paul Harness — Featuring Jupiter Bumblebee PIO Caps & High-Value Aged Pots

Bring the magic of a true golden-era Les Paul to life with this hand-wired vintage-spec harness, crafted for tone purists and vintage enthusiasts alike.

At the core are a pair of Jupiter paper-in-oil “Bumblebee” capacitors .015uf for the neck and .022uf for the bridge — some of the finest modern reproductions available. These caps deliver a smooth, harmonically rich high end with the warm, detailed response that made late ’50s Gibsons legendary.

The potentiometers in this harness are something truly special: WD Music Custom CTS Pots - each one is carefully tested and electrically hand aged one at a time by me — not just for tone, but for character. Bringing the measured values ranging from 600k to around 650k, these values closely mirror what’s commonly found in original ’50s and early ’60s Les Pauls, where the actual pot values often read well above the nominal 500k rating. This higher resistance opens up the top end, tightens the lows, and adds clarity and presence — especially helpful for bringing out the best in vintage-style humbuckers. The Custom CTS Pots also have a very smooth audio taper and yes they do that thing from 8-10!

Wired with vintage-correct 1950s-style wiring, this harness preserves high-end detail when rolling back volume and delivers a dynamic, touch-sensitive response that modern circuits often miss.

Perfect for vintage restorations, custom builds, or tonal upgrades, this harness captures the soul of a true vintage Les Paul — no fluff, no shortcuts, just real-deal tone.
