Boss CH-1chat_bubble_outlineFrom real comments

A subtle, transparent chorus that many players keep on their board for decades. Multiple long-term owners describe using the CH-1 since the 80s or 90s and never looking back, valuing its handy effect-level and EQ knobs. Users like the way it blends into the guitar and amp tone without being overwhelming, making it feel like an enhancer rather than a dramatic effect. It's described as neither too weak nor too over-the-top, suiting rhythm and lead playing alike as an always-on pedal for many genres.

Digital and analog versions reportedly sound nearly identical, though purists have preferences. Commenters note Boss quietly switched the CH-1 from analog BBD chips to a digital delay chip around 2001 without renaming it, and in blind tests the two are hard to distinguish. Some still track down older analog units for perceived clarity or warmth, while others say they prefer digital chorus overall. A few DIY users modified analog units with higher quality components to improve clarity and reduce volume drop.

Not everyone is a fan — some call it the worst Boss chorus for band mixes. A vocal minority strongly dislikes the CH-1, describing it as a horrid, garbage-sounding pedal that doesn't work well in a full band mix regardless of settings. Others report a softening, compressed, nasal quality that deadens the guitar signal, or complain the EQ knob barely does anything and output volume seems low next to overdrive pedals. These complaints coexist with many positive reviews, suggesting mixed but real dissatisfaction.
