Used BOSS CS3 Compressor Sustainer Effect Pedal

Used BOSS CS-3 Compressor/Sustainer in fair condition, delivering classic stompbox compression for smoother dynamics, added sustain, and snappy attack—great for guitar or bass. Features Level, Tone, Attack, and Sustain controls for quick shaping, plus rugged BOSS construction. Compact pedal format with standard 1/4-inch input/output and 9V operation (battery or PSA-style adapter). Expect visible wear, but solid performance for tightening clean parts, enhancing leads, and evening out funk rhythms.
