Traditional ’50s wiring. Premium components. Hand-wired by Carparelli.
Upgrade your Les Paul Junior’s electronics with a Carparelli pre-wired harness designed for one pickup, one volume and one tone control. Ideal for replacing worn components or converting a compatible PCB-equipped instrument to traditional hand-wired electronics.
The ’50s wiring arrangement connects the tone circuit to the volume control’s output, helping preserve clarity as you reduce the volume. The volume and tone controls interact, giving you an expressive range of adjustment directly from your guitar.
All three options use the same 0.022µF capacitance and 100V rating:
Select your preferred capacitor when ordering. Pricing varies by option.
The Pure Tone multi-contact jack is our standard choice, selected for its secure plug contact and dependable connection.
Prefer a Switchcraft jack? We stock them and can provide one by request. Please contact us before ordering to arrange your preferred configuration.
Control spacing: Standard volume-to-tone spacing is 60mm centre to centre. Measure your guitar before ordering. For different spacing, contact us to arrange a suitable configuration.
Pot shaft length: The CTS pots have 3/8" threaded collars. Confirm this length suits your guitar’s mounting thickness.
Mounting holes: CTS pots require approximately 3/8" (9.5mm) mounting holes. Instruments fitted with smaller metric pots may require careful enlargement of the existing holes.
Knob compatibility: Compatible imperial fine-spline knobs are required. Existing metric knobs may not fit.
Installation: Soldering is required to connect the pickup, bridge ground and output jack as applicable. PCB-equipped instruments may also require changes to their existing connectors.
Assembly or mounting template boards are not included.
Hand-wired craftsmanship for the heart of your guitar.

Testimonial from Ice – Shop Supervisor & Tone Inspector
“Hi, I’m Ice. I may not have opposable thumbs, but I do have an ear for tone and a nose for quality wood.
Every day I patrol the shop, sniffing out bad solder joints and ensuring every guitar smells like success (and maybe a little beef jerky).
Mike built me a custom dog-sized Telecaster once. I couldn’t play it... but I licked it. It passed inspection.
So if you're wondering whether to buy from Carparelli Guitars, here's my advice: Sit. Stay. Buy it. 5 paws out of 5.
Now please excuse me while I nap in a pile of tonewood.”
