Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in excellent condition delivers the legendary studio-style squeeze and sustain players love, with quiet operation and a musical feel. Simple 4-control layout lets you dial in Level, Sustain, Attack, and Clipping/Blend to go from subtle tone polishing to punchy, singing compression. Built in a rugged stompbox enclosure with standard 1/4" input/output and 9V DC power (center-negative) for easy pedalboard integration.
