42 AWG pickup wire is an ultra-fine enameled copper wire (magnet wire) specifically designed for high-precision coil winding applications such as guitar pickups, micro coils, and sensitive electronic components.
This magnet wire features a high-purity copper conductor with a plain enamel insulation coating. The thin insulation allows for extremely tight winding, making it ideal for applications that require high turn counts in limited space.
Due to its small diameter and excellent electrical properties, 42 AWG enameled copper wire is widely used in audio equipment, especially electric guitar pickups where tone and signal clarity are critical.

Applications
42 AWG enameled copper wire is widely used in precision and audio-related applications.
Guitar Pickups
The most common use of 42 AWG magnet wire is in electric guitar pickups. It helps produce balanced tone and clear signal output.
Audio Coils
Used in microphones, speakers, and audio transformers.
Precision Electronics
Suitable for small coils in sensors and signal devices.
Micro Coil Winding
Ideal for applications requiring very fine wire and high winding density.
Insulation Details
Plain enamel insulation provides:
- Thin coating for maximum copper fill
- Smooth surface for uniform winding
- Adequate electrical insulation for low-voltage applications
Compared with heavy insulation, plain enamel allows tighter coil structures and better space utilization.
