Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering studio-smooth sustain and punchy dynamics in a pedalboard-friendly format. Simple four-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in anything from subtle leveling to squashy country snap, with Clipping offering added grit and harmonic color. Rugged compact stompbox design with standard 1/4" input/output and 9V DC power (center-negative), ideal for guitar or bass rigs.
