Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor pedal in great condition, delivering classic studio-style squash, sustain, and sparkle for electric guitar or bass. Simple 4-knob control set lets you dial in compression, sustain, level, and clipping/attack response for everything from subtle leveling to country snap. Built in a rugged compact stompbox enclosure with true-bypass switching and standard 1/4" in/out, it runs on 9V DC center-negative power for easy pedalboard integration.
