Boss CS-3 Compression Sustainer Model Compressor Effect (1999), made in Taiwan, serial # QM08149, blue enamel finish. There are few pedals more recognizable and universally beloved by guitarists than the Boss line of effects pedals: affordable, produced en masse, and offered in a (now) classic array of bright colors. The CS-3 Compression Sustainer is a classic compression pedal, 'compressing' the louder bits of the signal and giving a boost to quieter bits with knobs for dialing in the exact amount of attack and sustain you desire. This pedal features a simple four knob layout that provided more versatility compared to its two predecessors the CS-1 (which only had a three-way switch to control tone and no attack control) or the CS-2 (which had no tone control).
