Used BOSS CS3 Compressor Sustainer Effect Pedal

Used BOSS CS-3 Compressor/Sustainer in great condition—perfect for smoothing dynamics, adding sustain, and tightening clean or driven tones. This compact, road-ready stompbox features Level, Tone, Attack, and Sustain controls for precise shaping, plus buffered bypass to maintain signal strength. Standard 1/4" input/output and runs on a 9V battery or PSA-style 9V DC adapter (not included). A classic choice for guitarists and bassists seeking studio-style compression on a pedalboard.
