Boss CE-1 Chorus Ensemble

The Boss CE-1 Chorus Ensemble, released in June 1976, was the first-ever chorus pedal and a groundbreaking innovation in effects pedal history. Derived from the chorus circuit in the Roland JC-120 Jazz Chorus amplifier, the CE-1 brought lush, stereo modulation to a standalone format. It featured both Chorus and Vibrato modes, each with dedicated controls, and was powered by an internal AC transformer. Built around the Matsushita MN3002 Bucket Brigade Device (BBD), the CE-1 delivered a warm, analog sound that became synonymous with '70s and '80s music. Though large and heavy compared to modern pedals, its rich tone and versatility made it an instant classic.

Historical Development

• Origins: The CE-1 was initially designed for keyboard players but quickly gained popularity among guitarists for its thick, spatial sound. It was one of the first pedals to utilize BBD technology, which allowed for compact analog modulation effects.
• Production: Manufactured in Japan until 1984, the CE-1 laid the foundation for Boss's legendary line of chorus pedals, including the compact CE-2 (released in 1979).
• Legacy: The CE-1 is considered one of the most influential effects pedals ever made, inspiring countless clones and digital recreations.

Notable Players

• Andy Summers (The Police): Used the CE-1 extensively to craft shimmering clean tones on tracks like "Walking on the Moon."
• John Frusciante (Red Hot Chili Peppers): Incorporated it into his rig for lush modulation on songs like "Scar Tissue."
• Eddie Van Halen: Known to use it subtly in stereo setups to enhance his clean tones.

Popular Settings

The CE-1's simple controls allow for a range of iconic sounds:

• Classic Chorus: Intensity at noon for a warm, dimensional sound perfect for clean rhythms.
• Subtle Vibrato: Depth at 10:00 and Rate at 9:00 for gentle pitch modulation.
• Leslie-Like Swirl: Vibrato mode with Depth maxed out and Rate at 3:00 for fast rotary speaker emulation.

Legacy

The Boss CE-1 Chorus Ensemble remains a landmark in effects pedal history. Its lush analog sound and dual functionality (chorus/vibrato) set a new standard for modulation effects. Though discontinued in 1984, its influence persists through modern recreations and its successors in Boss's chorus lineup. The CE-1 continues to be revered by musicians seeking its signature warm modulation and stereo depth.
