Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic Keeley studio-style squeeze with smooth sustain and enhanced clarity for guitar or bass. Four controls (Sustain, Level, Attack, and Clipping) make it easy to dial in everything from subtle leveling to punchy, percussive compression. Built in a rugged compact metal enclosure with standard 1/4" in/out jacks and 9V DC power (center-negative) for seamless pedalboard integration.
