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 added clarity. Simple four-control layout lets you dial in Level, Sustain, Attack, and Clipping/Blend to go from subtle leveling to punchy, country snap. Built in a rugged stompbox enclosure with standard 1/4" in/out and 9V DC (center-negative) power, it’s a reliable tone sweetener for stage or studio.
