Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition—an iconic stompbox for smooth sustain, added punch, and studio-style clarity on stage. Simple four-control layout lets you dial in Level, Sustain, Attack, and Clipping for everything from subtle leveling to rich, singing compression. Built in a rugged compact enclosure with standard 1/4" input/output and true bypass switching for an uncolored signal when off. A perfect upgrade for clean tones, country snap, and lead bloom.
