Boss CS3 Compression Sustainer Pedal

BOSS CS-3 Compression Sustainer Pedal

The BOSS CS-3 Compression Sustainer provides smooth, balanced compression for guitarists and bassists who want consistent tone, longer sustain, and precise dynamic control.
By compressing loud signals and boosting softer ones, the CS-3 creates a refined, professional sound that enhances clarity and sustain without sacrificing your instrument’s natural character.

With its low-noise design, intuitive controls, and signature BOSS reliability, the CS-3 is the perfect pedal for tightening your tone, leveling your dynamics, and achieving polished studio-quality sustain on stage or in the studio.

Smooth, Balanced Compression

The CS-3 delivers even, natural compression that retains the warmth and clarity of your original signal. It’s ideal for adding punch to rhythm parts, extending sustain for lead lines, or controlling peaks when switching between playing styles.

• Smooth, transparent compression for any playing style

• Evens out dynamics while preserving tone and feel

• Ideal for clean rhythm, sustained leads, or percussive funk tones

Precision Control and Tone Shaping

With Level, Tone, Attack, and Sustain knobs, the CS-3 offers detailed control over your sound.
Adjust the Attack to shape response speed, fine-tune Tone to brighten or darken your sound, and use Sustain to control how long notes ring out.

• Level sets output volume

• Tone adjusts overall brightness

• Attack defines the compression response

• Sustain controls compression amount and sustain length

Low-Noise, High-Quality Design

Built with high-quality circuitry, the CS-3 delivers quiet, stable performance with minimal signal noise—even at high compression settings.
Its durable BOSS construction ensures years of reliable use, whether on stage or in the studio.
