Handwired in Canada with Emerson Pro CTS Pots, Pure Tone Jack & Emerson Bumblebee PIO Caps

Product Description

Upgrade your Les Paul with a premium hand wired harness built for vintage tone, smoother control response, and professional reliability.

The Carparelli Pro Les Paul 50’s Wiring Harness is carefully hand wired in Canada using high-quality USA-spec components, including CTS 500K split-shaft potentiometers, a Pure Tone multi-contact mono jack, vintage-style braided shield wire, and your choice of Emerson Bumblebee Paper-in-Oil capacitors.

This harness is wired in the classic 1950’s Les Paul style, a favourite among players looking for a more open, dynamic, and responsive feel from their volume and tone controls.

Built for USA Gibson Les Paul-style guitars and premium LP-style builds. Import guitars may require minor hole enlargement and USA-spec knobs.

What’s Included

• 4 x CTS 500K Split-Shaft Potentiometers
• 1 x Pure Tone Multi-Contact 1/4" Mono Jack
• Vintage-style braided shield wire
• Your choice of Emerson Bumblebee Paper-in-Oil capacitors:

Capacitor Option 1 — Vintage Woman Tone Setup

• 0.015uF Neck
• 0.022uF Bridge

This option gives the neck pickup a smoother, creamier roll-off while keeping the bridge strong, clear, and classic.

Capacitor Option 2 — Traditional Les Paul Setup

• 0.022uF Neck
• 0.022uF Bridge

This is the classic balanced LP setup, great for rock, blues, classic rock, hard rock, and all-around vintage humbucker tone.

• 1 x Wiring diagram PDF or paper copy

Note: Prewired 3-way toggle switch is sold separately, or available as part of our Les Paul 5A Kit.

Why 50’s Style Wiring?

50’s wiring is loved because it keeps your guitar more alive and responsive when using the controls.

With standard modern wiring, rolling back the volume often causes treble loss. With 50’s wiring, more clarity remains as you lower the volume, making it easier to clean up an overdriven amp without your tone becoming muddy or disappearing in the mix.

The result is a more dynamic playing experience with:

• Stronger, clearer tone
• Better treble retention when rolling down volume
• More responsive volume and tone controls
• Smoother control sweep
• Excellent amp cleanup from the guitar’s volume knob
• A more vintage-correct Les Paul feel

The volume and tone controls will interact slightly with each other, just like many classic vintage circuits. That interaction is part of what gives 50’s wiring its expressive, old-school character.

Built for Serious Tone

This harness is ideal for players upgrading from factory electronics, import wiring, or lower-grade components. The combination of Emerson Pro CTS pots, Paper-in-Oil Bumblebee capacitors, braided shield wire, and the Pure Tone multi-contact jack delivers a noticeable improvement in reliability, feel, and tonal response.

Whether you are building a new Les Paul-style guitar or upgrading an existing one, this harness gives your pickups the quality electronics they deserve.

Compatibility Notes

Designed for USA Gibson Les Paul-style guitars and other LP-style guitars routed for USA-spec electronics.

For import guitars, some modification may be required:

• Pot holes may need to be enlarged to fit USA-spec potentiometers
• USA-spec push-on knobs may be required
• These pots use 24-spline split shafts
• Some import knobs will not fit properly

Please check your guitar before ordering, especially if installing into Epiphone or other import LP-style guitars.

Installation Tip for Split-Shaft Pots

Emerson Pro split-shaft pots are designed for USA-spec 24-spline push-on knobs.

Do not force a tight knob onto the shaft. If a knob feels too tight, gently compress the split shaft slightly before installation. Pressing too hard can damage the pot shaft or push it through the pot.

Take your time during installation, and contact us with any questions before forcing parts together.

The Carparelli Pro Les Paul 50’s Wiring Harness is a serious upgrade for players who want better control, better clarity, and a more vintage-correct response from their Les Paul.
