Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering smooth, studio-style compression that adds sustain, clarity, and punch without squashing your tone. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in anything from subtle leveling to country snap and lead sustain. Built in a rugged compact stompbox enclosure for standard pedalboards, it runs on 9V DC center-negative power and works perfectly with guitar or bass rigs.
