Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in good condition, delivering classic studio-style compression for guitar and bass. Four intuitive controls—Sustain, Level, Attack, and Clipping—let you dial in everything from subtle leveling to punchy, country snap with enhanced clarity. Built in a rugged stompbox enclosure with true-bypass switching and standard 1/4" input/output. A go-to pedal for smoothing dynamics, adding sustain, and tightening your tone without sacrificing feel.
