Boss CH-1 Super Chorus Pedal | No Limit Guitar Co, Idaho Falls
The Boss CH-1 Super Chorus is arguably the best-selling chorus pedal on the planet — a clean, shimmering, endlessly versatile chorus stompbox that has become a fixture on guitar and keyboard rigs worldwide. Four onboard controls — Effect Level, EQ, Rate, and Depth — put the full range of classic chorus character within easy reach, from subtle, clean shimmer to lush, wide stereo ambience to boat-rocking, dizzying psychedelic swirls. Two outputs enable a rich, wide stereo chorus effect that gives any guitar or keyboard rig genuine spatial motion on stage and in the studio. Part of BOSS's lineup of over 10 million pedals sold worldwide to players including Yngwie Malmsteen, Steve Vai, and John Petrucci, the CH-1 is housed in BOSS's signature rugged metal enclosure and built to stomp night after night.
Product Overview
Chorus is one of the most fundamental and widely used modulation effects in guitar and keyboard playing — the subtle pitch and timing variations it introduces to a signal add width, dimension, and movement to a tone in a way that is often felt as much as consciously heard. The CH-1's four controls give players comprehensive command over this character without unnecessary complexity. Effect Level controls how much of the wet chorus signal blends with the dry tone, allowing everything from a nearly transparent sheen to a fully pronounced chorus effect. The EQ control shapes the tonal character of the effected signal — brightening or mellowing the chorus tone to suit different guitars, keyboards, and playing styles.
Rate controls the speed of the chorus modulation — set slowly for a smooth, gentle movement that adds subtle width and shimmer without obvious wobble, or cranked higher for the faster, dizzying swirl that transforms a clean tone into something genuinely psychedelic. Depth controls how dramatic the pitch modulation within the chorus effect is — lower depth settings for a more transparent, chorus-inflected tone, and higher depth settings for a thicker, more pronounced, lush effect. The combination of Rate and Depth across their respective ranges gives the CH-1 a genuinely wide range of chorus character — the same four-knob layout that produces a barely-there shimmer on one guitarist's board can produce a slow, deep, dramatic swell on another's, all from the same pedal.
Two outputs unlock the CH-1's full stereo potential. Connecting both outputs to two amplifiers or two channels of a mixing desk produces a rich, wide stereo chorus effect that places the modulation in genuine spatial motion across the stereo field — a significant sonic upgrade from the mono-output version of the same effect, and particularly impactful for keyboard players who want their instrument to fill a stage or studio space with immersive, moving chorus texture. The -95dBu residual noise level ensures the CH-1's chorus signal remains clean and professional-quality even at higher effect level and depth settings.
