Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in good condition, delivering classic studio-style compression for guitar with smooth sustain and improved note clarity. Simple 4-control layout lets you quickly dial in Level, Sustain, Attack, and Clipping/Blend-style tone shaping (model dependent) for anything from subtle leveling to squashed country snap. Built in a compact, road-ready metal enclosure with standard 1/4" in/out and 9V DC power for easy pedalboard integration.
