BOSS CH-1 Super Chorus Guitar Effects Pedal

Classic Chorus, Refined

The Boss CH-1 Super Chorus is the go-to chorus pedal for guitarists and keyboardists who demand clean, shimmering modulation. With intuitive controls for Level, EQ, Rate, and Depth, the CH-1 lets you dial in anything from a subtle thickening to a wide, enveloping swirl — all with the clarity and reliability Boss is known for.

Crystal-Clear Stereo Sound

The CH-1's stereo circuitry delivers a crisp, nuanced chorus at every setting. Run the left and right outputs to two amps for a wide, immersive spread, or blend to mono for a focused, stage-ready tone. Either way, the CH-1 maintains exceptional clarity without coloring your dry signal.

Flexible Controls

• Effect Level — Set the chorus blend from a faint thickening to full modulation
• EQ — Cut or boost midrange frequencies to suit guitar or keys
• Rate — Control the speed of the modulation sweep
• Depth — Dial in the intensity from subtle to far-reaching

Road-Ready Build

Built to Boss's legendary standards, the CH-1 features a rugged metal chassis and footswitch designed for years of live performance. Simple, no-nonsense controls make it easy to adjust on the fly. Powered by a 9V battery or optional power supply (sold separately).
