Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic studio-style squeeze that made this pedal a staple for guitarists. Dial in smooth sustain and punchy attack with intuitive Level, Sustain, Attack, and Clipping controls, from subtle leveling to country snap and lead bloom. Built in a rugged compact stompbox with true bypass switching, standard 1/4" in/out jacks, and 9V DC power (center-negative) for easy pedalboard integration.
