The BOSS CH-1 Super Chorus pedal produces lush, shimmering chorus effects perfect for guitarists and keyboardists. With its intuitive controls for effect level, EQ, rate and depth, the CH-1 allows musicians to sculpt a chorus tone tailored to their needs. Whether seeking a subtle thickening effect or an intense, psychedelic swirl, the CH-1 delivers.

Crystal-Clear Stereo Sound

The CH-1 produces a crisp, nuanced chorus thanks to its stereo circuitry. Musicians can send the left and right outputs to two amps for a wide, enveloping chorus or blend the signals together for a focused mono tone. No matter the routing, the CH-1 maintains exceptional clarity.

Flexible, Versatile Controls

At the heart of the CH-1 are four knobs that shape its lush chorus sounds. The effect level knob determines how present the chorus effect is in the overall tone, allowing anything from a faint thickening to an all-encompassing sea of modulation. The EQ knob cuts or boosts midrange frequencies to suit different instruments or music styles. The rate and depth knobs control the speed and intensity of the modulation for chorus tones ranging from subtle and slow to frantic and far-reaching.

Road-Ready and Built to Last

Like all BOSS pedals, the CH-1 features a durable metal chassis and footswitches designed to stand up to years of performance use. Its simple, no-nonsense interface makes it easy to adjust on the fly, perfect for crafting chorus sounds on stage. Powered by a 9V battery or optional power supply (sold separately), the CH-1 provides peace of mind that it will continue enhancing your tone night after night.
