The Boss CH-1 Super Chorus is a classic compact chorus pedal capable of everything from subtle clean-guitar shimmer to wide, pronounced modulation.

Four straightforward controls for Effect Level, EQ, Rate and Depth make it easy to shape the amount, tone, speed and intensity of the chorus, while dual outputs allow either conventional mono operation or a much wider stereo setup.

This pre-owned example is presented in Good Condition, showing noticeable cosmetic wear consistent with previous use while remaining fully functional. No power supply is included.

What Makes The Boss CH-1 Super Chorus Special?

The CH-1 Super Chorus has become a long-running Boss favourite because it provides clear, versatile chorus sounds without unnecessary complexity. Effect Level controls how prominently the modulation sits against the original guitar signal, while Rate and Depth determine the speed and intensity of the movement.

The dedicated EQ control adds another useful dimension, allowing the chorus to be made warmer and smoother or brighter and more pronounced. Dual outputs also make the CH-1 particularly effective in stereo rigs, where the wet and dry signals can be spread across separate amplifiers.

Key Features & Benefits

Effect Level

Controls how much chorus is blended with the original signal, making it easy to move from very subtle enhancement to a much more obvious effect.

EQ Control

The EQ control changes the tonal character of the effected signal. Lower settings produce a warmer sound, while higher settings introduce additional brightness and sparkle.

Rate Control

Adjusts the speed of the chorus modulation, from slow and spacious movement through to faster swirling textures.

Depth Control

Determines the intensity of the modulation, allowing gentle thickening or much deeper chorus effects.

Mono & Stereo Outputs

The CH-1 can feed a conventional mono amplifier or be connected to two amplifiers for a significantly wider stereo chorus effect.

Boss Buffered Bypass

Boss's buffered bypass system helps maintain a strong signal through longer cable runs and larger pedalboards.

Comparison Against Popular Alternatives

Boss CH-1 vs Boss CE-2W

The CE-2W concentrates on vintage-inspired Boss and Roland chorus sounds, while the CH-1 provides additional control through dedicated EQ and Effect Level knobs and is a particularly flexible everyday chorus.

Boss CH-1 vs Boss CE-5 Chorus Ensemble

Both offer highly adjustable chorus effects. The CH-1 keeps its interface particularly direct, using a single EQ control alongside Rate, Depth and Effect Level.

Chorus vs Flanger

Chorus generally creates a smooth sense of width and movement, while flanging has a more pronounced sweeping and comb-filtered character. The CH-1 is ideal when musical depth and spaciousness are the priority.

Who Is It For?

Clean guitar players – Adds width and movement without dramatically changing the core guitar tone.

Rock guitarists – Excellent for broadening clean passages, arpeggios and lead sounds.

Indie and alternative players – Chorus remains a key effect for atmospheric and textural guitar parts.

Funk and pop guitarists – Subtle settings can add dimension while retaining clear rhythmic attack.

Pedalboard users – Compact Boss construction and simple controls make it easy to integrate into almost any conventional effects setup.

Suitable Genres & Applications

Particularly well suited to:

• Pop
• Rock
• Classic rock
• Indie
• Alternative
• Funk
• New wave
• Shoegaze
• Ambient
• Clean rhythm guitar
• Arpeggios
• Lead guitar
• Stereo rigs
• Pedalboards
• Home recording
• Live performance

Why Choose A Chorus Pedal?

Chorus is one of the easiest ways to make a single guitar sound broader and more spacious without adding significant gain or delay.

At subtle settings it can simply add extra dimension to chords and arpeggios. Increasing Rate and Depth creates a much more obvious modulated texture that can become a defining part of the guitar sound.

The CH-1 makes these sounds particularly accessible through a simple four-control layout.
