Used BOSS CS-1 COMPRESSION SUSTAINER Effect Pedal

Classic sustain and tone shaping await with this used BOSS CS-1 Compression Sustainer, a vintage pedal from the late '70s to early '80s. Featuring Level and Sustain controls and two compression modes (Normal and Treble), it delivers a distinctive, punchy response. In fair condition with cosmetic wear from age and use, this rare silver screw unit runs on a 9V battery or ACA adapter. A must-have for collectors or tone-hunters seeking retro dynamics.
