An Iconic BOSS Chorus, Built for Stage and Studio
The CH-1 follows in the footsteps of BOSS choruses that have become pedalboard standards: a clear, defined modulation effect that is immediately "mix-ready." Its identity is based on a silky modulation with a pronounced stereo spaciousness while maintaining clarity in the attacks. Within the BOSS range, it stands as a reliable choice for those seeking a versatile chorus without complex settings, but with real shaping possibilities thanks to the EQ.For Which Musicians and Styles?
The BOSS Super Chorus CH-1 is aimed both at beginners who want a simple and effective chorus and at experienced guitarists looking for reliable modulation live. It excels in pop, funk, rock, new wave, and worship, and pairs very well with clean tones, light crunch, or delays/reverbs for wider soundscapes. It is also suitable for keyboards, to broaden the sound of Rhodes, organ, or pads, whether in rehearsal, studio, or on stage.Technical specifications
