Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in good condition, delivering the classic, studio-style squash and sustain guitarists love. Four easy controls—Sustain, Level, Attack, and Clipping—let you dial in everything from subtle leveling to punchy country snap, while the clipping switch adds a touch of grit when desired. Built in a rugged compact enclosure, it runs on standard 9V DC center-negative power and fits neatly on any pedalboard for reliable tone shaping night after night.
