This vintage cloth spaghetti tubing replicates the original yellow insulating sleeves used in classic electronics and vintage guitars, such as Fender and Gibson models. Manufactured to match the appearance and quality of mid-20th-century materials, it is designed specifically for restoring or replicating vintage electronics with historical accuracy.
The tubing is crafted to fit #20 AWG wire, making it ideal for insulating ground connections between potentiometers in vintage Gibson guitars. Its braided glass fibre cloth construction is hand-coated to an high quality finish, ensuring durability and authenticity.

Historical Use
Professional Varnished Glass-Fiber Insulation Sleeving (Spaghetti Tubing)
Designed specifically for vintage amplifier restorations, classic effects pedals, high-end studio gear, and precision point-to-point wiring (Fender, Gibson, Neumann, and boutique builds). Our professional-grade varnished glass-fiber sleeves provide maximum thermal and electrical protection for component leads, capacitors, and resistors.
Authentic Vintage Look & Feel: Recreates the exact aesthetic and period-correct construction required for high-end vintage restorations.
Historical Accuracy Across Eras & Gear: Essential for period-correct builds and restorations of legendary gear across the golden eras of audio—from 1950s Tweed and Blackface Fender amplifiers, late-60s Marshall Plexi circuits, vintage fuzz/boost pedals, up to classic studio microphones (such as vintage Neumann tube condensers) and microphone preamplifiers.
Thermal & Dielectric Protection: Excellent resistance to high temperatures from soldering irons and tube-amp/studio gear operating heat, preventing short circuits and component damage in tight spaces.
Easy to Work With: Flexible, highly durable 20 AWG size that slides effortlessly over cloth-covered wire, vintage paper-in-oil capacitors, and resistor leads.
Essential for Builders & Techs: The go-to choice for amp techs, pedal builders, studio microphone restorers, and custom craftsmen who refuse to compromise on historical accuracy and reliability
This style of insulation was widely used in the 1940s, 1950s, and into the 1960s in various applications, including:
- Guitars: Iconic models like the Gibson Les Paul and Fender instruments.
- Amplifiers: Vintage amp circuitry.
- Radios and Electronics: Common in consumer and professional electronics of the era.
Gibson employed this tubing for ground jumper wire insulation throughout the 1950s, while Fender extended its use for short connections and jumpers into the early 1960s.
