98:, a Los Angeles, California guitarist, began experimentation with electric amplification of the guitar. Originally using a phonograph pickup assembly, Beauchamp began testing many different combinations of coils and magnets trying to create the first electromagnetic guitar pickup. His earliest coils were wound using a motor from a washing machine. Later on he switched to a sewing machine motor, and eventually used single coiled magnets.

wound and reverse polarity middle pickup that when in combination with the normal bridge or neck pickups will cancel electromagnetic interference (noise/hum) which single coil pickups suffer badly from. The sonic effect of positions 2 and 4 is sometimes referred to as a "quack" or "notch positions", and some guitar notation includes directions to use these pickup combinations. One example is "

The neck pickup features a metal cover and produces a mellower sound, while the bridge pickup has exposed pole pieces and produces an extremely twangy, sharp tone with exaggerated treble response, because the bridge pickup is mounted on a steel plate.

Early pickup designs did not include a manufacturing step known as "potting", wherein at various stages, the bobbin and wrapped coil are immersed in a substance in order to lock the windings in place and prevent microphonic effects of loose strands of wire within resulting in feedback at higher gain

Valco single coil pickups by Ralph Keller (1954) can be found in
Airline, Supro, National, English Electronics, Custom Kraft, and a few Gretsch models of guitar from the '50s, '60s, and '70s. The majority of these pickups maintain the physical appearance of a larger, double coil humbucker pickup.

Christian's close association with the ES-150 it began being referred to as the "Charlie Christian Model" and Gibson's now famous bar pickup as the "Charlie Christian pickup" or "CC unit".
349:. Other examples may include playing near older fluorescent lamps with magnetic ballasts, or high frequency switching DC power supplied from mains power "wall wart" units commonly provided with consumer electronics, computers and smartphones.

The practice of not "potting" pickups persists today in both vintage reproductions as well as more value oriented manufacturers, who may skip the potting step in order to reduce manufacturing costs or provide period accurate reproductions.

The search for an acceptable solution to mains hum gained new impetus around 1995 as guitar players became increasingly intolerant of the low noise environment required for single-coil use.
