Boss CS-3 Compression Sustainer
Boss · pedal
The Boss CS-3 Compression Sustainer is a compressor pedal that evens out picking dynamics and adds smooth, natural sustain without an obvious pumping or breathing artifact. Its Level, Attack, and Sustain controls let players dial in anything from a light dynamics leveler that stays mostly transparent to a heavily compressed, thick, sustain-heavy tone for lead lines. True bypass keeps the signal unaffected when off. It suits blues and rock players wanting reliable, musical sustain and dynamic control from a straightforward, road-ready pedal.
