The History of Chorus Pedals for Guitar
Origins and Early Beginnings
Chorus pedals for guitar, essential components in the modern guitarist's toolkit, have a rich history that traces back to the early days of music electrification. The chorus effect simulates the sensation of multiple instruments playing the same note simultaneously, creating a fuller and more vibrant sound. This sonic modulation originated from recording and tape manipulation techniques in the 1950s and 1960s.
Predecessors to the Chorus: Studio Techniques
Before chorus pedals became common, sound engineers created similar effects using studio techniques. In the 1960s, bands like The Beatles and The Beach Boys experimented with “double-tracking,” where recordings of the same guitar or vocal line were slightly detuned or time-shifted to create a richer and fuller sound. This technique was a direct precursor to the chorus effect.
The First Chorus Pedals
The 1970s marked the transition from studio to stage. The advent of the first chorus pedals was a milestone in this movement. Electro-Harmonix was one of the pioneers with the release of the Electric Mistress in 1975. This pedal combined flanger and chorus effects and quickly became popular among guitarists looking to enhance their live sound.
However, the first pedal dedicated exclusively to the chorus effect was the Boss CE-1 Chorus Ensemble, released in 1976. This groundbreaking pedal brought studio-quality sound to live performers. Based on the circuit from the legendary Roland Jazz Chorus amplifier, the CE-1 offered simple controls and a deep, organic sound that captured the imagination of many musicians.
Evolution and Popularization
With the success of the Boss CE-1, the chorus pedal market flourished. In the 1980s, chorus pedals became ubiquitous in popular music. The Boss CE-2, launched in 1979, was a more compact and affordable version of the CE-1, and its characteristic sound defined chorus for a generation of musicians. This pedal is often associated with the crystalline and expansive sound of new wave and 80s rock.
Other companies quickly followed suit. Ibanez introduced the CS9, and MXR released the M134 Stereo Chorus, both helping to diversify the tonal options available to guitarists. The chorus became a signature sound of the era, appearing in iconic albums and live performances.
Chorus in the Modern Context
As the 1990s and 2000s arrived, the popularity of chorus pedals fluctuated with the emergence of new musical trends. However, chorus never disappeared completely. Instead, manufacturers began exploring new variations and combinations of effects. Pedals like the Electro-Harmonix Small Clone, popularized by Kurt Cobain of Nirvana, introduced a new generation to the classic chorus sound.
In the current landscape, chorus pedals continue to evolve. With the rise of digital technology, pedals like the Strymon Ola and the TC Electronic Corona Chorus offer a vast range of sounds and customizations, blending the best of analog and digital technologies. These pedals provide guitarists with unprecedented flexibility, combining complex modulation effects in a single, compact device.
The Legacy of Chorus
The chorus pedal remains an essential tool for guitarists across all musical genres, from pop and rock to jazz and metal. Its characteristic sound, ranging from subtle shimmering to deep and rich undulations, continues to inspire musicians to explore new textures and sonic landscapes.
The history of chorus pedals is a testament to the ongoing innovation in the world of music, reflecting the relentless pursuit of new sounds and artistic expression. From its origins in studio techniques to modern technological advancements, the chorus continues to be a central piece in the sonic palette of guitarists worldwide.
