CS-3 Compression Sustainer

The BOSS CS-3 Compression Sustainer is an analog compressor pedal designed to provide natural compression and extended sustain without adding distortion. Its controls include Level for output volume, Tone for adjusting the high-frequency response, Attack for setting how quickly compression engages, and Sustain for controlling the amount of compression and sustain. A high-performance VCA circuit delivers stable, balanced compression with low noise, preserving clarity across a wide range of playing styles. The pedal features buffered bypass and is designed to smooth signal dynamics while maintaining articulation, making it suitable for everything from clean rhythm playing to sustained lead tones.
