Boss CS-2 Compression Sustainer
The CS-2 compresses high-input signals while boosting low-input signals, giving you smooth and long sustain without degrading the quality of the original sound. The CS-2 uses a VCA (Voltage Controlled Amplifier) instead of the photocouplers used by the CS-1. The VCA’s speeds up the signal processing and makes the attack much faster compared to the CS-1. The Attack knob can however be used to control this.
