Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition—an industry-standard stompbox for smooth sustain, tighter dynamics, and studio-style clarity on any pedalboard. Simple 4-control layout (Sustain, Level, Attack, and Clipping) makes it easy to dial in everything from subtle leveling to punchy country snap. Designed for electric guitar with true bypass switching and rugged compact housing, it delivers low-noise compression that enhances clean tones and adds focus to overdriven sounds.
