The legendary BOSS CH-1 Super Chorus pedal provides guitarists and keyboardists alike with a palette of lush, shimmering sounds. For over three decades, the CH-1 has been a staple on pedalboards around the world thanks to its simple interface and versatility. The CH-1 Super Chorus is a must-have for crafting dimensional tones in any musical style.

Dial in Iconic Chorus Effects

With just four intuitive controls—Level, EQ, Rate, and Depth—you can sculpt a chorus tone that's all your own. Crank the Rate knob to dizzying speeds for a psychedelic swirl or back it off for a gentle, undulating effect. The Depth control determines how intense the effect becomes, while the Level dial allows you to blend the wet and dry signals to taste. An EQ knob lets you shape the overall tone, boosting highs for a shimmery sheen or rounding out the low end for a warmer, more analog-style chorus.

Take Advantage of Legendary BOSS Reliability

Like all BOSS pedals, the CH-1 Super Chorus is built to withstand years of regular use. Its roadworthy metal chassis and durable footswitches are ready to handle gigs played on stages around the world. Inside, high-quality components provide consistent, noise-free performance for the lifetime of the pedal. With over 10 million pedals sold, BOSS is an industry leader you can depend on.

Unlock a Wide Stereo Soundstage

For the ultimate in dimensional, spacious tones, use the CH-1's stereo outputs to connect to two amplifiers. Twist the Depth control to maximum and revel in the swirling, oceanic sounds that fill the room. Dialing back the Depth while increasing the Rate results in a crystalline effect ideal for ambient and post-rock styles. In the studio, the CH-1's stereo functionality gives guitar and keyboard tracks a sense of space and airiness that translates beautifully to the final mix.

A Gateway to Creative Expression

Whether you're looking to add subtle texture or all-out psychedelia to your playing, the BOSS CH-1 Super Chorus pedal provides a gateway to new creative possibilities. Its simple interface invites experimentation, allowing you to twist knobs and be rewarded with inspiring sounds. A perennial classic, the CH-1 Super Chorus belongs on the pedalboard of any guitarist or keyboardist seeking to expand their tonal palette.
