The invention of the humbucking electric guitar pickup revolutionized the world of electric guitars by eliminating unwanted electrical interference and producing a rich, noise-free tone.
In the early days of electric guitars, single-coil pickups were commonly used. While these pickups were effective in converting string vibrations into electrical signals, they were also susceptible to external electromagnetic interference, commonly known as hum. This interference caused an audible hum or buzz in the signal, particularly in environments with electrical equipment or strong radio waves.
The humbucking pickup was invented by Seth Lover, an engineer working for Gibson Guitar Corporation in the 1950s. Lover's goal was to develop a pickup that would cancel out the unwanted hum while maintaining the tonal characteristics of a single-coil pickup.
The key innovation in Lover's design was the use of two coils instead of one. Each coil was wound in opposite directions, with one coil connected in reverse polarity to the other. This arrangement allowed the coils to capture the string vibrations but cancel out the hum by virtue of the opposite winding and polarity.
The first commercially produced humbucking pickup was introduced by Gibson in 1957 as the "PAF" (Patent Applied For) pickup. These early PAF pickups were featured on Gibson's high-end electric guitars, including the Les Paul models. The PAF pickups gained popularity due to their ability to provide a warm, full-bodied tone while effectively eliminating hum.
Gibson sought to protect their invention by applying "PAF" stickers to the backs of their humbucking pickups. Later, they applied stickers with a patent number to the pickups, and they came to be referred to as "patent number" pickups. This was actually a bluff, however, as the patent number referred to on the stickers was for the patent they had secured for the adjustable bridge on their guitars.
Over the years, other guitar manufacturers started incorporating humbucking pickups into their instruments, recognizing their benefits. The humbucker became a defining characteristic of many iconic electric guitars, including the Gibson SG, Fender Stratocaster HSS (Humbucker/Single-Coil/Single-Coil) models, and countless others.
As time went on, various variations and improvements were made to the original humbucking pickup design. These modifications included changes in magnet types, coil winding techniques, and the introduction of different wiring options, such as coil splitting and tapping. These advancements allowed players to achieve a wider range of tones and versatility.
Today, humbucking pickups remain a staple in the electric guitar world. They are favored by musicians across different genres for their noise-canceling capabilities and the distinct, fat tone they produce. The invention of the humbucking pickup by Seth Lover continues to shape the sound of modern electric guitars and has become an integral part of the instrument's evolution.
